In this article, cotton is modified by m- DMDHEU and choline chloride. The modified cotton can adsorb and ion exchange ion CrO4 2- , H2AsO4 - in water solution as effectively as anionit resin. The material are activated by soaking in 24 h with mixed m-DMDHEU and choline chloride, then dried and activated in 1 h at 140 oC, all residual reactants was removed by water. Adsorption and ion exchange process were studied with a model solution contained ion CrO4 2- , H2AsO4 - in different conditions. Results showed that the modified cotton is able to adsorb ion CrO4 2- , H2AsO4 - of the model, solution is nearly completely, respectively 99,95 % and 99,60 %; the values of anionit resin is respectively 97,99 % and 97,60 % at pH=7,0.
