| 摘 要： | 对粘土矿物吸附水溶液中镉离子进行了研究。对吸附的机理、吸附剂用量、pH值、吸附剂粘径、离子强度进行了实验探讨。研究结果表明，Langmuir吸附等温方程式与吸附实验相符；溶液的pH值越大，越有利于吸附；吸附剂的粒径越小，吸附效果越好；离子强度对吸附过程的影响很小。

| Abstract: | The adsorption of aqueous cadmium solution by low_cost mineral silicate was studied. The results show that the better adsorption isotherm is Langmuir equation; the adsorption increases as the particle size of adsorbent decreases; with the increase of pH, the adsorption also increases; whereas the effect of ionic strength is little. |
