| 摘 要： | 通过静态吸附试验,研究一种由超分子受体化合物磺化硫杂杯芳烃(TCAS)与树脂结合的产物-新型TCAS树脂对水体中三氯甲烷的吸附去除性能.结果表明,对于25 mL质量浓度为1mg·L~(-1)的三氯甲烷污染水,投加0.5g TCAS树脂吸附40min后,去除率可达99％以上.TCAS树脂对三氯甲烷吸附的操作温度应控制在5～15℃左右为最佳.pH是影响TCAS树脂吸附效果的重要因素,在pH=6～8时去除效果较好.Ca~(2+)和Mg~(2+)背景阳离子的存在会加快TCAS树脂对三氯甲烷的吸附速率.在试验范围内,TCAS树脂对三氯甲烷吸附符合Freundlich方程.伪二级反应动力学方程能够较好地描述TCAS树脂对三氯甲烷的吸附过程. |

| Abstract: | Through the static tests, the capacity of a new TCAS-adsorbed resin to remove of aqueous chloroform was investigated. This TCAS-adsorbed resin was made of a novel supramolecular compound named thiacalix4]arenetetrasulfonate (TCAS) and anion exchange resin. The results indicated that the TCAS-adsorbed resin could effectively adsorb chloroform. The removal rate of chloroform in aqueous solution was up to 99% after 40 min when a 25 mL aqueous solution of chloroform (1.0 mg·L~(-1)) was adsorbed by 0.5 g TCAS-adsorbed resin.Ca~(2+) and Mg~(2+) accelerated the adsorption. The isothermal adsorption of TCAS-adsorbed resin for chloroform fitted Freundlich equation within the range of experimental concentration. The adsorption of chloroform by TCAS-adsorbed resin followed the pseudo second-order kinetic mode. |
