Strong cation exchanger 2-hydroxy-3-sulfpropyl-cellulose Na salt is prepared by modified cellulose of corn straw with ClCH_2CH(OH)CH_2SO_3Na . Further,its adsorption properties has been studied for cationic turquoise, Pb~(2+), Cu~(2+). The result shows that the modified cellulose of corn straw has stronger adsorption ability to cation and its regeneration is easy.
