In this study, Prunus Cerasus Rock (PCR) and Poly (Styrene - co- Maleic Anhydride) modified with Melamine-Oxalic acid (SMA-MO) were used to prepare a cheap adsorbent through chemical modification. The maximum removal was observed at pH = 6.0 and adsorbent dose 1.5 g/L for initial Nickel -ions concentration 30 mg/L. Study of temperature effect proved that the process is endothermic. Langmuir and Freundlich isotherm models were used for equilibrium adsorption data. Langmuir isotherm proved to be a better fit. Pseudo first order and pseudo second order kinetic models were applied to analyze the kinetic mechanism of adsorption.
在本研究中，采用樱桃李岩（PCR）和用三聚氰胺-草酸改性的聚（苯乙烯-马来酸酐）（SMA-MO）通过化学改性制备了一种廉价吸附剂。对于初始镍离子浓度为30 mg/L的情况，在pH = 6.0和吸附剂剂量为1.5 g/L时观察到最大去除率。温度效应研究证明该过程是吸热的。采用朗缪尔和弗伦德利希等温线模型对平衡吸附数据进行拟合。结果表明，朗缪尔等温线拟合效果更好。应用伪一级和伪二级动力学模型分析吸附的动力学机制。
