STUDY ON ENRICHMENT AND SEPARATION OF TRACE Pd（Ⅱ） WHITH SILICA GEL BONDED BY （BENZOYLAZO—ARSENAZO I）—AMINOPROPYL

This Paper reports enrichment and sepqration of trace Pd(Ⅱ）with silica gel bonded by (benzolyazo-arsenazo I)-aminopropyl(BAAI·SG).BAAI·SG is stable in solution between 6 mol/L HCl and pH 9.0.The maximum adsorptive capacities of BAAI·SG and SG are 52.7,23.5μmol/g respectively.After preconcentration through BAII·SG column,Pd(Ⅱ）of ppb level in artificial water samples can be measured by spectrophotometry.
