介绍了制备高锰酸钾改性鸡蛋壳吸附剂的方法,并分析了其去除水中铜离子的效果与机理,表征结果表明,高锰酸钾改性鸡蛋壳对铜离子的吸附量远大于单纯鸡蛋壳的吸附量;吸附动力学和等温线的结果表明,改性鸡蛋壳对铜离子的吸附机理为单层吸附机制,p H值和吸附剂量对吸附过程的影响显著,然而离子强度对吸附过程的影响较小。
The preparation method of potassium permanganate modified egg shell adsorbent was introduced and its effect and mechanism of removing copper ion in water were analyzed. The results showed that the adsorption capacity of copper ion by potassium permanganate modified egg shell was far greater than that of pure The results of adsorption kinetics and isotherms showed that the adsorption mechanism of copper ion in the modified egg shell was monolayer adsorption mechanism, the influence of p H value and adsorbent dose on the adsorption process was significant, however, the adsorption of ionic strength on adsorption The impact of the process is small.
