Natural zeolite was used for the removal of malachite green (MG) from aqueous solution in batch mode and reused by microwave irradiation. The isotherm data were analyzed by the Langmuir, Freundlich, Redlich-Peterson, and Koble-Corrigan isotherm model. The better fit for the equilibrium process was Koble-Corrigan model. The kinetic studies indicated that the adsorption followed the pseudo-second-order kinetic. Thermodynamic calculations showed that the adsorption was spontaneous and endothermic process. Spent zeolite was treated by microwave irradiation and it was found that yield of regeneration was 85.8% in the case of microwave irradiated time 10 min at 160 W.
天然沸石用于从水溶液中批量去除孔雀石绿（MG），并通过微波辐射重复使用。通过 Langmuir、Freundlich、Redlich-Peterson 和 Koble-Corrigan 等温模型对等温线数据进行了分析。平衡过程的更好拟合是 Koble-Corrigan 模型。动力学研究表明，吸附遵循拟二级动力学。热力学计算表明，吸附是自发和吸热的过程。用过的沸石用微波辐射处理，发现微波辐射 160 W 10 分钟时的再生收率为 85.8%。
