| 摘 要： | 用1-(2-吡啶偶氮)-2-萘酚-6-磺酸(PAN-S)水溶液处理201×7强碱性阴离子交换树脂,制取了具有PAN-S功能团的PAN-S浸渍树脂.用PAN-S作显色剂测定水相中金属Ni~(2+),建立了分光光度测定方法,并且研究了测试的优化条件以及PAN-S浸渍树脂对金属Ni~(2+)的静态吸附和动力学吸附行为.结果表明,在288～318K和研究的浓度范围内,PAN-S浸渍树脂对金属Ni~(2+)的吸附平衡数据符合Freundlich和Langmuir吸附等温方程,其吸附金属Ni~(2+)为放热过程,适当降低温度有利于吸附.

| Abstract: | The PAN-S resin was prepared by treating the 201×7 ion-exchange resin with 1-(2-pyridylazo)-2-naphthol-6-suiphonic acid. Spectrophotometry was adopted and optimized to determine the concentration of Ni~(2+) in the solution and 1-(2-pyridylazo)-2-naphthol-6-suiphonic acid was used as the chromogenic reagent, the detection wavelength was 550nm. The static and dynamic adsorption characteristics of Ni~(2+) on the PAN-S resin were investigated in this paper.The results indicated that the Langmuir and Freundlich models gave perfect fitting to the isotherm data and the adsorption of Ni~(2+) on the PAN-S resin is a kind of exothermal process within the temperature range of 288～318K. |
