Desizing process of cotton fabric by ammonium persulfate-sodium bisulfite system;

Effects of foliage spraying sodium bisulfite on photosynthetic physiological characteristics of Citrus sinensis with sulphur deficiency;

In the synthesis of menadione sodium bisulfite(MSB),the traditional raw material 2-meth- yl-1,4-naphthoquinone(2-MNQ) contains 6-methyl-1,4-naphthoquinone(6-MNQ),resulting in lower content of the product.
