Abstract

Copolymer resins (8-HQSABF) were synthesized by the condensation of 8-hydroxyquinoline-5-sulphonic acid and biuret with formaldehyde in the presence of hydrochloric acid as catalyst, proved to be selective chelation ion exchange copolymer resins for certain metals. Chelation ion exchange properties to these polymers were studied for Cu2+, Cd2+, Co2+and Zn2+ions. A batch equilibrium method was employed in the study of the selectivity of the distribution of a given metal ions between the polymer sample and a solution containing the metal ion. The study was carried out over a wide pH range and in a media of various ions strengths. The polymer showed a higher selectivity for Cu2+ions than for Cd2+, Co2+and Zn2+ions. Hence on the basis of above studies these copolymer may be used as semiconductors, surface coating, ion-exchangers, materials for rechargeable battery cell in various electronic industries, plastic materials, elastomers and in boiler plants

Highlights

Ion exchange may be defined as the reversible exchange of ions between the substrate and surrounding medium
For no resin based on 8-hydroxyquinoline-5-sulphonic acid, biuret and formaldehyde in acidic media has been synthesized for the quantitative separation of transition metal ions
In order to estimate the time required to reach the state of equilibrium under the given experimental conditions, a series of experiments of the type describe above were carried out, in which the metal ion taken up by the chelating resins was determined from time to time at 25 °C

Summary

Introduction

Ion exchange may be defined as the reversible exchange of ions between the substrate and surrounding medium. The chelating behavior of the prepared resin was studied with Cu(II), Zn(II), Ni(II), Cd(II) and Pb(II) metal ions. For no resin based on 8-hydroxyquinoline-5-sulphonic acid, biuret and formaldehyde in acidic media has been synthesized for the quantitative separation of transition metal ions.
