摘要
膨润土对溶液中Ｃｕ￣（２＋）离子的吸附量随样品中蒙脱石的含量、可交换性阳离子容量以及母液的初始浓度而变化，当母液浓度增加到一定数值后，吸附量达到极限值，不再随母液浓度的增加而变化。膨润土对Ｃｕ￣（２＋）离子的吸附等温线属Ⅰ类吸附等温线，且符合Ｌａｎｇｍｉｕｒ吸附等温方程。
Amount of Cu￣(2+) absorbed by Bentonite in solution varies with quality of Montrnoril-lonite in clay,quality of exchangeable cations in clay and with consistency of Cu￣(2+)in solu-tion.But amount of absorption does′t increase with consistency that get up high enough.The curve of absorption on equal─temperature belong in first type of B.E.T.The curve accord with Langmiur Equation.
