When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).

但是由于凹凸棒石孔道直径小于大多数分子及水合离子的直径,除少数简单分子和离子外,多数分子和离子都不能进入凹凸棒石孔道,而且凹凸棒石选择性吸附水分子,因而在多数情况下,凹凸棒石对吸附质的吸附不是内表面吸附,而是外表面吸附。并且外表面吸附是胶体和离子交换吸附。本文阐述了凹凸棒石的孔道直径、吸附选择性、体系pH 值及凹凸棒石和蒙脱石胶体颗粒的互相作用对凹凸棒石吸附性能应用的制约。
