改性CMC聚合物吸附酸法地浸废水中的铀
Acid leaching uranium-containing wastewater treatment by modified CMC polymer
摘要
Abstract
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.关键词
