摘要

本工作提出利用吸附现象来解决水中重金属污染的问题。用表面活性剂α-烯烃磺酸盐对活性炭表面进行改性，以提高活性炭对镉的吸附能力。测定了接触时间和初始浓度对吸附过程的影响。对未改性和表面活性剂改性炭对镉的吸收的研究表明，表面活性剂修饰的活性炭的镉吸收能力比未改性的活性炭提高了两倍。

Cadmium Removal by Adsorption: Enhancement by Surfactant Mediation

This work proposes to tackle the problem of heavy metal contamination of water, using adsorption phenomenon. We have tried to enhance the adsorptive cadmium uptake capacity of activated carbon by modifying its surface with the surfactant - Alpha olefin sulfonate. The effect of contact time and the initial concentration on the adsorption process has been determined. Study of the cadmium uptake by both the unmodified and surfactant modified carbon, with the adsorption data fitted to adsorption isotherms, showed the cadmium uptake capacity of the surfactant modified activated carbon to have enhanced two-fold over the unmodified activated carbon.
