| Abstract: | A kind of ion-exchange membrane with strong acid and weak acid groups was prepared by radiation-induced grafting of acrylic
acid (AA) and sodium styrene sulfonate (SSS) onto high-density polyethylene membrane (HDPE). The effect of additives such
as sodium acetate, sodium chloride on grafting yield was studied. It was found that for either pre-irradiation method or simultaneous
radiation method, the weak acid salt of strong alkali sodium acetate had a complex effect on the grafting yield by “pH effect”
and “ion pair effect”, and the neutral salt sodium chloride was helpful to the increase of grafting yield by “ion pair effect”. |
