摘　　要：采用间歇实验,考察了初始pH、柚子皮投加量、柚子皮粒径、离子强度、染料初始含量及接触时间对柚子皮去除废水中的活性艳蓝KN-R及活性艳橙X-GN这2种染料影响。结果表明,酸性pH条件下吸附效果良好,柚子皮能有效地去除废水中的KN-R和X-GN,对KN-R和X-GN的去除率达到97.48%和95.63%;柚子皮粒径变化对吸附效果影响不明显,吸附时间宜控制在480 min以上。柚子皮可作为一种新型吸附剂应用于活性染料废水的处理,作为一种农业废物的资源化加以利用。Shaddock peel was used to treated wastewater containing reactive brilliant blue （KN-R） or reactive orange （X-GN） as adsorbent. In this study, the effects of initial pH, adsorbent dosage, adsorbent diameter, ionic strength, dye concentration and contact time on dye removal were investigated with batch experiments. The results showed that shaddock peel was an effective adsorbent to remove KN-R and X-GN from aqueous solutions. The adsorption process was favorable at acid pH and the removal rate of KN-R and X-GN reached 97.48% and 95.63%, respectively. The change of adsorbent size had very little effect on dye removal and contact time should be regulated at more than 480 rain. It indicated that shaddoek peel was a new, effective bioadsorbent for active-dye wastewater.
