| 摘 要： | 利用柚子皮纤维素制备新型黄原酸酯(SCX),对废水中Cd2 进行吸附研究。通过对影响其吸附效果的SCX用量、Cd2 初始浓度、pH值、反应温度、吸附时间等因素进行吸附实验。结果表明:当废水中Cd2 初始浓度为15mg/L时,0.022gSCX对Cd2 去除率高达99.36%,其吸附容量达33.87mg/g,具有良好的吸附性。SCX对Cd2 的吸附符合Langmiur和Freundlich方程。

| Abstract: | Xanthate was prepared by using shaddock peel cellulose.The product was then used to remove Cd~(2 )from simulated wastewater.The adsorption experiments discovered that adsorption affect was controlled by the initial concentration of Cd~(2 ),pH values in wastewater,adsorption period,the consumption of xanthate and the reaction temperature.The results also show that the rate of the removal of Cd~(2 ) by xanthate of 0.022g can reach up to 99.36% and the adsorption capacity 33.87mg/g when the initial concentration of Cd~(2 )in wastewater is 15mg/L.Xanthate,which has favorable adsorption characteristics for Cd~(2 ).The adsorption process could be simulated by both Freundlich and Langmuir,which equation. |
