摘要 以纤维素为母体,硫脲为功能基团合成新型吸附剂CMT,利用FTIR,SEM,元素分析和TG对样品进行了表征,并对阳离子染料碱性品红溶液进行了吸附实验,考察了pH,吸附剂用量,温度,吸附时间对吸附过程的影响,对吸附动力学和吸附等温线进行了研究.结果表明,CMT在最佳吸附条件下,对碱性品红的吸附率达到了92%,具有良好的吸附性能. A novel type of adsorbent（CMT） was synthesized by cellulose modified with thiourea to adsorption basic fuchsine in this work.The synthesized adsorbent was characterized by FTIR,SEM,elemental analysis and TG.The influence of different experimental parameters such as pH,contact time,temperature and adsorbent dosage on removal process was evaluated;the kinetics studies and adsorption isotherms were investigated.The removal percentage of basic fuchsine was 92% when the initial concentration of basic fuchsine was 25 mg·L-1.
