Title resins containing 2.30(mmol and 2.57 (mmol functionalgroups have been prepared. The intermediate resin with] adjacent dihydroxyl groups was prepared in a phase transfer catalysis system with high percentage of conversion of functi. onal group. In aq. HC1 solution
the sulfite resin absorbs Pt (II) selectively
title resins absorb Au (III) with high selectivity in the presence of Fe(II)
Zn(II)
Cd(II)
Ni(II)
Cu (II)
Pd(II)
Pt(IV)
Pb(II)
Mn(II). The sulfite resin has the capacity 126 mg Au(m)/g
separation coefficient Kd=824 (ml/g)
and the Au(III) adsorbed can be eluted to 85% with ne eluting. The carbonate resin has the capacity 46.0 mg Au (III)/g
