## 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
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 \(\mathrm{HCl}\)
