| 摘 要： | 通过异丙醇（20%）改性后的柚子皮对水中Cr6＋的吸附实验,研究pH值、吸附时间、吸附剂的投加量及Cr6＋初始浓度对吸附性能的影响。结果表明：当pH=5,Cr6＋初始浓度为35μg/mL,吸附时间为45min,吸附剂的投加量为6g/L时,吸附效果最佳,去除率达到99.88%。

| Abstract: | The influences of factors such as pH value,contact time,adding dosage of adsorbent and Cr6+ initial concentration on the adsorption results were discussed through the adsorption experiment on shaddock peel modified by isopropanol.The results indicated that modified shaddock peel had good adsorption to Cr6+.The optimal conditions of absorption were as follows: the value of pH was 5,the initial concentration of Cr6+ was 35μg/mL,the reaction time was 45 min,and the dosage of absorbent was 6g/L,the adsorption rate of Cr6+ could be up to 99.88%. |
