摘　　要：根据蛭石的国内外研究现状,采用颗粒蛭石为吸附剂,分析研究其对于亚甲基蓝的吸附性能,探索了不同时间、浓度和蛭石量对亚甲基蓝的吸附量和去除率影响规律。实验结果表明,当颗粒蛭石0.5 g和亚甲基蓝浓度为100 mg/kg时,在240 min左右达到吸附平衡;吸附液的p H值应大于7时效果最佳;蛭石与亚甲基蓝的最高比为1∶425。通过本课题蛭石对染料吸附性能的研究,将对蛭石在水处理中的应用具有一定的指导意义。Based on home and abroad research progress for vermiculite, the adsorption performance of methyleneblue was studied by using granular vermiculite as adsorbent. The adsorption capacity and removal rate of methylene bluewere explored at different time, concentration and vermiculite. The experiment results showed that the granule vermiculitereached the adsorption equilibrium at 240 rain for 0. 5 g vermiculite in 100 mg/kg methylene blue solution, the pH ofadsorption solution should be greater than 7, and the highest ratio of vermiculite to methylene blue was 1 ： 425. Throughthe study of the adsorption properties of vermiculite onguiding significance.the dyes, the application of vermiculite in water treatment had some
