摘　　要： 为了探索柚皮粉去除染料废水的效果,采用柚皮粉作为吸附材料吸附去除模拟废水中的中性红,重点研究了柚皮粉在不同的吸附剂投加量、振荡时间、中性红的初始浓度、温度等实验条件下对中性红的吸附规律及吸附效果.结果显示:当温度为30℃时,0.3 g柚皮粉在100 mL质量浓度为150 mg/L的中性红溶液中振荡60 min后,中性红的去除率达到80%以上,最大吸附量为49.20 mg/g.柚皮粉对中性红的吸附过程可以用Temkin吸附等温方程和二级吸附速率方程进行很好的描述,吸附过程主要为物理吸附. In order to explore the effect of the peel powder on the removal of dye wastewater, using peel powder as absorbent material, the simulated wastewater was collocated with the neutral red. The effects of such factors as dosage of peel powder, shaking time, the initial concentration of neutral red, temperature and so on, were investigated. The results show that when the temperature is 30 ℃, the removal rate of neutral red reaches more than 80% , the maximum absorption capacity is 49.20 mg/g in the neutral red concentration of 150 mg/L, peel powder 0.3 g/100 mL, shaking 60 min. The isothermal absorption equation and secondary absorption rate equation of Temkin can be used to describe the absorption process of peel powder to neutral red, and the main absorption process is physical absorption.
