A Water-soluble temperature sensitive polymer, polyNIPAAm, was synthesized by radiation technology in H,2,O-THF mixed solutions and further, in simple alcohols, ketones and Cl-containing organic compounds as the solvents. The results showed that all the synthesis was successful. Several polyNIPAAm with different molecular weight were obtained in this way. In addition, the concentration effects of Au,2+, in dilute aqueous solutions was investigated by using polyNIPAAm obtained in this work. The concentration coefficient could come up to more than 90%. The effects of acidity and concentration coefficient in the solution were investigated. The optimum conditions were obtained.
