| 摘 要： | 以柚子皮纤维素、硫代乙醇酸为基本原料,制备巯基纤维素(SC)新型吸附剂,用其对含Cu2 的溶液进行了静态吸附研究。本文探讨了Cu2 初始浓度、pH值、吸附时间、反应温度、吸附剂用量等因素对吸附性能的影响,结果表明:在pH为6.5、Cu2 浓度为100mg/L和吸附剂为0.2g时,常温条件下吸附2h后Cu2 去除率和吸附容量分别达到98.03%和24.5068mg/g,吸附反应符合Langmuir和Freundlich等温方程。

| Abstract: | The sulfur-containing cellulose(SC) was a new type absorbent prepared by using shaddock peel cellulose and thioglycollic acid.The product was then used to remove Cu2 from simulated wastewater.The adsorption experiments discovered that adsorption affect was controlled by the initial concentration of Cu2 ,pH values in wastewater,adsorption period,the consumption of SC and the reaction temperature.The results also showed that the rate of the removal of Cu2 by SC of 0.2g could get up to 98.03% and the adsorption capacity was up to 24.5068 mg/g when the initial concentration of Cu2 in wastewater was100mg/L,pH values was 6.5,adsorption period was 2h,and room temperature.The adsorption isotherms could be well fitted by both Langmuir and Freundlich equation. |
