A novel polyvinyl alcohol/alginate/zeolite nanohybrid adsorbent for the adsorption of Ni(II) and Co(II) metal ions was prepared by the casting method. The prepared adsorbent was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy as well as Barrett‐Joyner‐Halenda and Brunauer‐Emmett‐Teller analyses. The optimum adsorption conditions in terms of content of zeolite nanoparticles, adsorbent dosage, and initial pH were determined. The kinetic data for both ions were well described by the double‐exponential kinetic model. The obtained Langmuir maximum adsorption capacities of Ni(II) and Co(II) metal ions were 81.51 and 79.58 mg g−1, respectively. The adsorption/desorption experiments showed a good performance after 5 cycles of adsorption.

聚乙烯醇/藻酸盐/沸石纳米杂化金属去除剂
通过流延法制备了一种新型的聚乙烯醇/藻酸盐/沸石纳米杂化吸附剂,用于吸附Ni(II)和Co(II)金属离子。制备的吸附剂通过傅立叶变换红外光谱,扫描电子显微镜以及Barrett-Joyner-Halenda和Brunauer-Emmett-Teller分析进行了表征。确定了根据沸石纳米颗粒的含量,吸附剂的用量和初始pH值的最佳吸附条件。双指数动力学模型很好地描述了两种离子的动力学数据。所获得的Ni(II)和Co(II)金属离子的Langmuir最大吸附容量分别为81.51和79.58mg g -1。吸附/解吸实验显示了5个吸附循环后的良好性能。
