Abstract

The aim of the study is to research of the adsorption properties of heavy metal ions Pb2+, Cd2+ and Ni2+ from industrial wastewater. For the adsorption of heavy metal ions, natural clinoptilolite was used, which belongs to the Ai-Dag deposit of the Tovuz-Kazakh region of Azerbaijan. Isotherms and kinetic curves of adsorption of heavy metal ions Pb2+, Cd2+ and Ni2+ were determined. The dependence of the adsorption of heavy metal ions on the pH value is also shown. It was revealed that the separation process proceeds more intensively at pH values of 5-6. It has been established that the maximum adsorption capacity of the clinoptilolite adsorbent for adsorption of Pb2+, Cd 2+ and Ni2+ ions is 7.5, 6.7 and 5.9 mmol/g, respectively.

重金属离子的吸附

本研究旨在研究工业废水中重金属离子 Pb2+、Cd2+ 和 Ni2+ 的吸附特性。重金属离子的吸附使用了阿塞拜疆托武兹-卡扎赫地区艾-达格矿床的天然铮亮石。测定了重金属离子 Pb2+、Cd2+ 和 Ni2+ 的吸附等温线和动力学曲线。同时还显示了重金属离子的吸附与 pH 值的关系。结果表明，在 pH 值为 5-6 时，分离过程进行得更为剧烈。结果表明，clinoptilolite 吸附剂对 Pb2+、Cd 2+ 和 Ni2+ 离子的最大吸附容量分别为 7.5、6.7 和 5.9 mmol/g。
