摘　　要：以桔子皮为原料,采用1 mol/L的磷酸溶液对桔子皮进行改性.考察吸附剂用量、染料初始质量浓度、吸附时间、吸附温度及pH值等因素对吸附性能的影响.结果表明,改性后桔子皮吸附能力明显提高,吸附条件为:桔子皮用量为0.2 g、染料活性艳红染料的初始质量浓度为20 mg/L、吸附时间为30 min、温度在25℃、pH=2.0时,吸附率达到93.67%.Using orange peel as an adsorbent,the orange peel was modified with 1 mol/L phosphoric acid solution.The effects of various experimental parameters such as adsorbent dosage initial,dye concentration,contact time,adsorption temperature and pH etc were examined.The results indicated that the adsorption rate was significantly enhanced with orange peels modification.The adsorption rate of reactive brilliant red X-3B was enhanced up to 93.67 % in solution with 0.2 g adsorbent,initial reactive brilliant red X-3B concentration of 20 mg/L,contact time of 30 min,adsorption temperature 25 ℃,and pH 2.0.
