摘要
文章以蛭石、粉煤灰、沸石为吸附材料,初步研究了它们对Cr6+离子的吸附性能。实验表明,3种吸附剂对Cr6+离子的吸附都受到吸附剂量、溶液pH和搅拌时间等吸附条件的影响。经过对照实验,表明蛭石对Cr6+离子的吸附效果较之粉煤灰和沸石要好,并且在如下吸附工艺条件下:pH 5.5、搅拌时间30min、浓度为10mg/L的Cr6+模拟废水中,蛭石用量为0.1 g/ml最佳,此时最大去除率为70.11%。
In this paper, vermiculite, fly ash, zeolite for the adsorbent materials, on their performance Cr6＋ Ion conduct a preliminary study.The experiments show that their capacity of absorbing are subject to the weight of adsorbent, pH and adsorption contact time.The control experiments show that the vermiculite to Cr6＋ absorption effect is better than the fly ash and zeolite, its absorption of the best conditions： pH 5.5, Stirring time 30 rain, The concentration of 10 mg/1 of Cr6＋ wastewater in the vermiculite amount of 0.1g/ml forthe best, then the largest removal of 70.11 percent.
