%X The adsorption of uranium(VI) onto modified CMC was studied in this experiment.The result showed that the adsorption effect of modified CMC polymer was good,the grafting rate was above 68%,when temperature was 70~80 ℃,monomers quality concentration was 30%~35%,mass ratio was 10∶ 2.5,contact time was 3.5~4 h.The optimum experimental conditions were CMC quality concentration of 0.10 g/L,temperature of 25 ℃,pH=5.0,contact time of 100 min,under the optimal conditions,the removal rate of U(VI) was 97.1%,which increased about 21% on an average.Orthogenesis test is also showed that factors affecting adsorption from strong to weak were CMC dose,pH,contact time and temperature.
