摘要:
Cr(VI)是电镀工业中经常使用的一种重金属，也是电镀废液中难以处理的主要污染源之一。氧化石墨烯作为一种新型的单层二维材料，是一种优良的重金属离子吸附材料。本文成功制备了氧化石墨烯/四氧化三铁磁性复合材料，并以Cr(VI)为目标离子，对其吸附分离性能进行了研究。结果表明，Cr(VI)的初始浓度和溶液pH对吸附量和去除率均有一定影响。pH为2时，吸附效果最好。动力学过程模拟和等温吸附模型模拟结果表明，该吸附材料与铬离子的吸附数据更符合准二级动力学方程和Langmuir吸附模型。
Abstract:
Cr(VI) is a kind of heavy metal which is often used in electroplating industry, and it’s also one of the main pollution sources which is difficult to remove in electroplating wastewater. Graphene oxide, as a new type of two-dimensional single layer material, is an excellent material for heavy metal ion adsorption. In this paper, graphene oxide and ferric oxide magnetic composites were successfully prepared and the adsorption and separation properties of magnetic composites were studied with Cr(VI) as the target ion. The results showed that the initial concentration of Cr(VI) and pH had certain effects on adsorption capacity and removal efficiency. When the pH was 2, the adsorption effect was the best. The results of kinetic process simulation and isothermal adsorption model simulation showed that the adsorption data of chromium ion on the adsorbent were more in line with quasi-second-order kinetic equation and Langmuir adsorption model.
