摘要:
研究了PAN-S浸渍树脂对Co2+的吸附性能。Co2+吸附pH值范围为4.7~9.2,最佳pH值为5.4;达到最大吸附容量需25 min,树脂对Co2+平衡吸附容量是98 mg/g干树脂,达到最大吸附容量平衡时用0.1 mol/L的HNO3洗脱,洗脱率达98%。该方法建立了PAN-S-树脂富集-分离钴离子的分光光度测定方法,结果令人满意。

Abstract:
This paper has studies theresearch of PAN S impregnating resin on the properties of the adsorption of Co2+. The adsorption pH range of Co2+ is 4.7~4.7 and the optimum pH is 5.4; the time needed to reach maximum adsorption capacity of Co2+is 25 min and resin adsorption capacity for Co2+ balance is 98 mg/g dry resin; elution rate was 98% when the adsorption capacity reached maximum balance and eluted with 0.1 mol/L HNO3.The spectrophotometric method of PAN-S-resin enrichment and separation of cobalt ions were established and satisfactory results were obtained.
