Study of Chelating Ion Exchange Resin Containing 8-Hydroxy Quinoline and Separation of Metal Ions by Selective Sorption on the Resin Column

Abstract

Chelating ion exchange resin was synthesised from oxine
(8-hydroxy quinoline)-resorcinol-formaldehyde. The physicochemical
properties like % moisture content, true density of resin
(d_res), apparent density of resin (d_col), void volume fraction, total
exchange capacity, rate of exchange, interruption test, salt splitting
capacity, thermal stability, resin stability, pH study for metal ions,
effect of metal ion concentration on exchange capacity were
measured. The resin was characterised by IR and TGA. The quantitative
separation of copper-nickel. zinc-nickel was accomplished
by selective sorption on column.
