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. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
