摘要
化妆品废水中的色素、重金属离子、表面活性剂等污染物较难处理。采用甲醇溶剂的快速搅拌沉淀法制备的ZIF-8吸附剂,对化妆品废水中常见的色素(酸性红87、亮蓝FCF、酒石黄)及常见重金属残留(钡、铬、镍离子)进行了吸附性能研究,通过实验:污染物初始浓度(12 mg/L)、吸附时间(>60 min)、吸附剂用量>200 mg)、pH值等(中性偏弱酸性pH值在6~7)条件下,对化妆品废水中色素、重金属离子的吸附都能达到较好的效果。
It is difficult to treat pollutants such as pigments,heavy metal ions and surfactants in cosmetic wastewater.In this study,the adsorption performance of ZIF-8 adsorbent prepared by rapid stirring precipitation method with methanol solvent was studied for common pigments(acid red 87,brilliant blue FCF,tartrazine)and common heavy metal residues(barium,chromium,nickel ions)in cosmetics wastewater.Under the conditions of initial concentration of pollutants(12 mg/L),adsorption time(>60 min),adsorbent dosage(>200 mg),pH value(neutral to weak acid pH value between 6 and 7),the adsorption effect of pigment and heavy metal ions in cosmetic wastewater can achieve good results.
