Detailed Photos

 Used for trace analysis and determination of tellurium and niobium, as well as preparation of developer solutions, and also as a reducing agent;

The printing and dyeing industry, as a deoxidizer and bleach, is used for the cooking of various cotton fabrics, which can prevent local oxidation of cotton fibers and affect fiber strength, and improve the whiteness of the cooked fabric.

 

Reducing bleach has a bleaching effect on food and a strong inhibitory effect on oxidase in plant-based foods. According to Chinese regulations, it can be used for preserves with a maximum usage of 2.0g/kg;
