摘要
利用泥炭为原料制备出腐殖酸树脂,在动态条件下,研究了腐殖酸树脂对重金属离子Zn2+、Ni2+的吸附效果及吸附条件。结果表明,在20℃,流速为4mL/min,pH值为5.0～7.0,含Zn2+、Ni2+浓度分别为70mg/L的废水经过腐殖酸树脂处理,Zn2+、Ni2+去除率可达98%以上,且处理后的废水pH值近中性。含Zn2+、Ni2+浓度分别为32.5mg/L和29.4mg/L,pH值为5.9的电镀废水经腐殖酸树脂处理后,废水中Zn2+、Ni2+含量明显低于国家排放标准。
The humic acid resin is prepared with peat as material. Under the dynamic condition, the adsorption effect and conditions of humic acid resin against heavy metal ions such as Zn^2＋ and Ni^2＋ are studied. The result shows that the removing efficiency of Zn^2＋ and Ni^2＋ over 98% and the pH value near neutral after being treated by humic acid resin when waste water containing 70 mg/L of Zn^2＋ and Ni^2＋ , pH 5.0 - 7.0,the temperature is 20 ℃ and the flow speed is 4 mL/min. The electroplating waste water which containing 32.5 mg/L of Zn^2＋ and 29.4 mg/L of Ni^2 ＋ and pH 5.9 after absorbed by humic acid resin, the contents of Zn^2 ＋ and Ni^2＋ in waste water are prominently lower than discharge standard of China
