Product Description

Application Disodium bisulfite is a strong reducing agent, which has a wide range of applications: 1, widely used in the textile industry, as a reducing agent for reducing dye dyeing, reducing hair bleaching agent, reducing dye printing aid, silk refining and bleaching agent, stripping agent of dyeing material and cleaning agent of dyeing tank; 2, widely used in paper industry, used as mechanical pulp, hot grinding mechanical pulp and deinking pulp bleaching agent. It is the most suitable for wood pulp paper bleaching agent; 3, as a reduction bleaching agent is widely used in kaolin bleaching, fur bleaching and reduction whitening, bamboo products and straw products bleaching; 4, used in mineral processing and its sulfide synthesis; 5. Used as reducing agent in chemical industry; 6, food additives grade main Chemicalbook to be used in the food industry, widely used in preserves, dried fruits, dried vegetables, vermicelli, grapes. The identification test should be in 1% sample solution 10ml, adding copper sulfate test solution (TS-78)lml, should be gray black.  test solution (TS-193)lml to 1% sample solution 10ml, and the color of the test solution will disappear immediately. Sodium test (IT-28) was positive. For content analysis, 10ml of water was added to 10ml of formaldehyde test solution (TS-112), and after neutralization  test solution (TS-224), about 2g of accurately weighed samples were added, dissolved with water, and the volume was fixed to 500ml. Take 25ml of it and adjust the pH to 1.1 ~ 1.5 with lmol/L
