Abstract :
The stable adsorption complex is synthesized by Zn(II) and a inclusion complex of β-cyclodextrin resin and 8-hydroxyquinoline with epichlorohydrin as crosslinking agent. The adsorption complex was used as an adsorbent to study its adsorption performance on trace Zn(II) in water by atomic absorption spectrophotometry. The experiment researched adsorption and elution conditions and enrichment factor, and proposed a new method of trace Zn(II) enrichment and measurement. The results show that the synthetic resin has good absorption performance for Zn(II) and static adsorption capacity of 13.4 mg·g-1. EDTA(PH=7) was used for static elution, and the elution ratio reached 99% and concentration factor was 20 times. The method has been applied to the determination of trace Zinc in well water r samples with satisfactory results.
