Use

(1) Selenite reacts with sodium hydroxide to produce sodium selenite. Further refinement and addition of dilution agent to obtain the final product. (2) Selenium reacts with nitric acid to produce selenium oxide, which reacts with sodium hydroxide to produce sodium selenite. Followed drying and grinding to obtain the final product.
