✦ Synopsis

This paper reports on preconcentration and separation of trace (\mathrm{Pd}(\mathrm{II})) and (\mathrm{Pt}(\mathrm{IV})) with silica gel bonded by aminopropyl-benzoylazo-1-(2-pyridylazo)-2-naphthol (ABPN - SG). ABPN - SG is stable in solution between (6 \mathrm{~mol} /) liter (\mathrm{HCl}) and (\mathrm{pH}) 9.0. The maximum adsorptive capacity of (\mathrm{Pd}() II) on (\mathrm{ABPN}). SG is (96 \mu \mathrm{mol} / \mathrm{g}). After preconcentration and separation using an ABPN . SG column, Pd(II) and (\mathrm{Pt}(\mathrm{IV})) of (\mathrm{pph}) level in artificial water samples can be measured by spectrophotometry. (c) 1995 Academic Press, Ins.

## Abstract This paper reports a simple and highly selective method for preconcentrating and separating of trace Pd(II) and Pt(IV) with silica gel bonded by aminopropyl‐benzoylazo‐4‐(2‐pyridylazo)‐resorcinol (ABPR·SG). ABPR·SG is stable in solution from 6 mol/L HCl to pH 7.0 and in common organic s
