Plant with hydrazine hydrate _ _ Jinan MySpace chemical hydrazine hydrate FIG manufacturers

Hydrazine Hydrate analysis principles? Sample was added sulfuric acid to form a stable hydrazine sulfate, in the presence of sodium bicarbonate titrated with iodine solution to color indicate the end of excess iodine solution analysis points? Said vials must be added 5 ~ 10ml of water, said sample is about 0.04g (drop), said after the completion of the need to make up 50ml sample of distilled water. ? Added 1ml (1 + 5) after sulfuric acid can not add sodium bicarbonate immediately, we must allow the sample to form a stable hydrazine sulfate, add 1g of sodium bicarbonate, shake. ? Titration with iodine standard solution, the solution appeared yellow and keep 1min not disappear is the end of hydrazine hydrate can also be applied in the following areas: 1. precious metal cleaning, refining. 2. pickling and surface treatment solution for recovering metals. 3. processing waste and emissions. 4. Use of the electronic market in each grade refined sulfuric acid purification. 5. plastic and metal (nickel, cobalt, iron, chromium, etc.) metal inlays. 6. rocket fuel formulations. 7. ACTIRED used in the process, the process is mainly used in gold processing
