摘要
将天然沸石粉与易燃微粉按一定比例混合,挤压造粒,灼烧成多孔质天然沸石颗粒吸附剂,然后用于吸附Cr3+。试验了溶液pH、Cr3+初始质量浓度和吸附时间等因素对吸附性能的影响,绘制的吸附等温线近似符合Fre-undlich吸附等温方程。
The crude zeolite powder was mixed with a comhustible powder. The mixtere was changed into particle materials by extrtusion and a kind of porous zeolite particle adsorbent by high temperature calcination. This adsorbent was used to adsorb Cr^3＋ . The effect of pH, time and initial concentration of Cr^3＋ on adsorption reaction were investigated, respectively. The adsorption isothcrm drawn by the test data approximately fitted in Frcundlich adsorption isothermal equation.
