【Abstract】 This paper has investigated the absorption properties and regularities of foamed plastics laden with z-mercaptobenzothiazole for absorbing various ions. It shows that 0.2ppb of Ag+ can be quantitatively absorbed from aqueous solution sample. The rate of solution flowing through the column is 20ml/min. Thiourea is served as eluting agent. This way is regarded as a fresh and quick technique of enrichment.更多还原
