Nickel sulfate plays an important role in electroplating. It is the main salt for supplying nickel ions. Its concentration affects the efficiency of the cathode current and the performance of the coating. When the content is low, the dispersing ability is good, the crystal is fine, but the deposition speed is slow, and the anode and cathode current efficiency is low. When the content is high, the high current region deposits quickly, but the dispersing ability is poor, and the consumption is also large; magnesium sulfate is used as a conductive salt in the electroplating industry, and the plating solution can have better conductivity after being added to the nickel plating solution. Make the coating white and soft [1]. The analysis of nickel sulfate and magnesium sulfate in the electroplating solution generally adopts the EDTA complexometric titration method. Compared with the atomic absorption spectrometry, the method is simple in operation, low in cost, and has obvious end point sharpness and high precision. EDTA complexometric titration analysis of nickel and magnesium content Generally, ammonium fluoride masking agent is used to mask Mg2+, EDTA standard solution is used to determine Ni2+ content; in another sample liquid, Mg2+ and Ni2+ content are determined, and Mg2+ content is calculated by subtraction method [2] ]. Or the dimethylglyoxime precipitation method, the precipitation reaction of dimethylglyoxime with nickel, first determine the Mg2+ content by EDTA standard solution; determine the mixture of Mg2+ and Ni2+ in another sample solution, and calculate the Ni2+ content by subtraction method. However, the former's masking effect and masking time of the masking agent will affect the accuracy and precision of the measurement results [3]; the latter is difficult to obtain correct results due to the entrainment precipitation problem during the precipitation process. In this paper, the complexing constants of Mg2+, Ni2+ and EDTA are different. Ni2+ is determined by EDTA standard solution in HAc-NaAc medium with pH value of 5.5-6. At this time, Ni2+ can form stable complex with EDTA, while Mg2+ does not produce. Interference [4]; In another sample solution, the combined amount of Mg2+ and Ni2+ was determined by EDTA in an ammoniacal slow solution medium with a pH of 10, and the content of Mg2+ was calculated by subtraction method, and good experimental results were obtained. And this method was compared with ammonium fluoride masking method. The obtained results prove that the determination of Ni2+ and Mg2+ content by pH adjustment method is simpler and more feasible.

Sodium sulphate and magnesium sulphate are good veterinary drugs for diarrhea. They are commonly used for the treatment of intestinal constipation and cow's and sheep's rumen plots, and gastric valve obstruction. However, the following aspects should be taken into account when using it. The quantity of sodium sulfate and magnesium sulfate used for oral administration must have different characteristics and different effects. The use of small doses can promote gastrointestinal secretion, slightly enhance gastrointestinal motility, and have a stomachic effect. High-dose use has a role in diarrhea. Sodium sulfate stomach dosage 10 grams of pigs to 30 grams, cattle, horses, donkeys, quail 15 grams to 50 grams. The amount of diarrhea: pig 25 grams to 50 grams, 40 grams to 100 grams of sheep, cattle 400 grams to 800 grams, horses, donkeys, quail 200 grams to 500 grams. The amount of magnesium sulfate stomach: pigs 3 grams to 10 grams, cattle, horses, donkeys, quail 15 grams to 50 grams. The amount of diarrhea: pig 25 grams to 50 grams, 50 grams to 100 grams of sheep, cattle 300 grams to 800 grams, horses, donkeys, quails 200 grams to 500 grams. The concentration should be suitable for the concentration of sodium sulfate and magnesium sulfate solution is too small, most of the drugs will be absorbed by the intestinal wall after being taken by domestic animals, no diarrhea. If the concentration of the solution is too large (more than 10%), many adverse reactions will occur. As the following diarrhea prolonged, causing dehydration of sick animals, aggravate the condition; induce colitis or make the original enteritis increased. Practice has proved that it is appropriate to make it into a 5% to 6% solution.

WASHINGTON (reporter Feng power) July 4, AQSIQ quality sampling results released earlier this year with a base of 26 enterprises in Tianjin, Shanxi, Jiangsu and other 10 provinces and cities in the production of ammonium chloride. The total sampling pass rate is 94.1%. At the same time, the information also showed that at present, China's ammonium chloride output has accounted for 95% of the world's total production, while consumption accounts for 89% of the world total. When the Chinese Soda Industry Association expressed its opinion on the results of the spot check, at present there are 35 soda ash companies in China that produce ammonium chloride. The domestic production capacity is 5.2 million tons, and the global production of ammonium chloride was 5.47 million tons last year. Except for China, only Japan and India produce a small quantity. At present, China's major producers of ammonium chloride are Dalian Dahua Group, Hubei Shuanghuan Group and Tianjin Soda Plant. The total output of ammonium chloride from these three companies reached 2 million tons, accounting for half of the country's total output. In addition, there are 10 companies with annual output of about 200,000 tons. At the same time, China is still the largest consumer market for ammonium chloride. Last year, China imported 11 tons of agricultural ammonium chloride and 2,080 tons of industrial ammonium chloride. Ammonium chloride is a high-efficiency nitrogen fertilizer with a nitrogen content of about 25%. As ammonium chloride is lower in price than urea and other agricultural chemicals, it is welcomed by the market. In addition, ammonium chloride is an important raw material for compound fertilizers. Therefore, in recent years, ammonium chloride has become quite popular in the market. It is understood that the three companies that were found to have quality problems were small private enterprises. The quality problems of these enterprises are mainly due to the high residue content of ammonium chloride, low nitrogen content, and unreliable nutrient content of the packaging label. As of yesterday, Wenshui Wencheng Chemical Co., Ltd. of Shanxi Wenshui County had suspended the production and reorganization of the three small companies, and the other two unqualified products had been sealed and stored. The China Soda Ash Industry Association stated that this 94.1% pass rate indicates that the domestic product quality of ammonium chloride is completely guaranteed. The association has applied to the National Brand Strategy Promotion Committee for the application of 5 ammonium chloride products as "China Top Brand". The five companies are: Dalian Dahua Group Co., Ltd., Tianjin Haohai Chemical Co., Ltd. Tianjin Soda Plant, Hubei Shuanghuan Technology Co., Ltd., Jiangsu Debang Xinghua Chemical Co., Ltd., and Sichuan Zigong Honghe Chemical Co., Ltd.

At present, most of the rice in our province is in the period of heading and heading. Due to the recent rain and low temperatures, it is beneficial to the occurrence of rice smut. The disease can easily lead to a reduction in rice yield and affect the commodity nature of rice. Rice that contains more rice hull disease grains is generally not edible. Copper noble 27.12% basic copper sulfate suspension agent is a high-efficiency, broad-spectrum and environment-friendly fungicide produced by Newcomer of Australia (in Jiangsu sales contact phone number), registered for the prevention and treatment of false smut, rice blast, tomato early blight, Apple tree ringworm and citrus tree canker disease. For the prevention and treatment of rice smut, 5 to 7 days before the rice break and spray after the full shoot, each with a copper high 27.12% basic copper sulfate suspension 30 ml 30 kg water spray. After the occurrence of rice smut (more than 80% of rice smut disease reveals light yellow micro-organisms), the use of copper noble 27.12% basic copper sulphate suspending agent 50 ml of water plus 30 to 40 kg of spray per acre, can be pathogenic bacteria The bacteria in the block kill, so that the block shrinks and falls off when it is sunny, reducing the pollution of healthy grains. This medicine has the advantages of good efficacy, safety to crops, and good compatibility with other pesticides. Diluted with water before mixing, then mixed with other pesticides. The use of rice during late growth does not affect heading, and attention is paid to avoiding rice bloom application.
