Abstract:
Humic acid refined from humus acid was used for the modification of bentonite,and then the modified bentonite was used for the simultaneous adsorption of copper ions and 2,4-dichlorophenol. Experimental results indicated that the optimum adsorption could be achieved with 4 g/L adsorbent under room temperature for 100 mg/L mixed solution with pH 4—6 in 60 minutes,through which the maximum adsorption capacity for copper ions and 2,4-dichlorophenol was up to 23 mg/L and 16 mg/L,respectively. The adsorption was fitted well with Langmuir isotherm and the pseudo-second-order model.
摘要:
从腐殖酸中提取胡敏酸用于改性膨润土,并研究改性膨润土对铜离子和2,4-二氯苯酚混合液的吸附性能。实验结果表明:吸附剂量为4 g/L时,在室温和pH值为4~6的条件下,对100 mg/L的混合液吸附60 min后效果最好。改性土对铜离子最高吸附量达到23 mg/g,对2,4-二氯苯酚的最大吸附量达到16 mg/g。吸附符合Langmuir吸附等温方程以及伪二级动力学模式。
