摘　　要：为合理利用资源,提高资源利用率,研究了农林废弃物等各类生物质资源在环境保护领域的应用。采用柚子皮为原料,制备经柠檬酸改性的活性炭吸附剂,用于处理中性红染料并对其过程进行试验分析。探索了柠檬酸改性柚子皮基活性炭吸附剂对中性红染料的吸附机理,分析了吸附时间、吸附剂浓度、溶液pH值及吸附温度等因素对吸附效果的影响。试验结果表明,吸附时间、吸附温度及溶液pH值的增加,将有利于吸附过程的进行,吸附剂浓度的增加则会使得吸附过程的去除率呈现先增大后减小的现象,而吸附量持续降低。In order to make rational use of agricultural and forestry wastes and other resources,improve the utilization rate of resources and avoid the harm caused by environmental pollution to human beings.Pomelo peel is used as raw material to prepare activated carbon adsorbent modified by citric acid for the treatment of neutral red dye wastewater,and the process is analyzed experimentally.The adsorption mechanism of citric acid modified pomelo peel based activated carbon adsorbent for neutral red dye wastewater is studied.The effects of adsorption time,adsorbent concentration,pH value of red dye wastewater and adsorption temperature on the adsorption effect are analyzed.The results show that the increase of adsorption time,adsorption temperature and pH value of red dye wastewater will be conducive to the adsorption process.The increase of adsorbent concentration will make the removal rate of the adsorption process increase first and then decrease,while the adsorption capacity continues to decrease.
