Abstract
The inclusion complex of 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol with beta-cyclodextrin cross-linking polymer could react with various metal ions to form adsorbing complexes, In this paper the related exp eriment conditions and adsorption mechanism of enriching trace copper and nickel have been investigated, The results showed that in pH 4 sim ilar to 6 media the inclusion resin could enrich copper and nickel fro m dilute solutions. The multiple of enrichment were 50 and 200 for cop per and nickel, respectively.
