The strengthening effect of PUS_01 anionic starch used in Masson's pine branch pulp has been studied,and the optimal charge has been set up.

This paper focus on the study on anionic starch-aluminium as well as anionic starchformaldehyde combination tannage to manufacture wet-white leather.

The interaction mechanism of anionic starch in flotation separation of diaspore and illite from bauxite has been investigated by the flotation tests,zeta potential experiments and adsorption capacity measurements.
