REMOVAL OF LEAD (II) WITH POLY 3-(AZA-18-CROWN-6) SILICA BONDED PHASE FROM SUCCINATE MEDIUM AND SAMPLES ANALYSIS

Abstract

A method was described for the determination of micro amount of lead (II) with Poly 3-(Aza-18-crown-6) Silica bonded phase employed as an ion-pair forming a neutral complex from Sodium succinate medium (0.01 to 3.0 M). The adsorbed ion-pair complex was back eluted with 0.5 M hydrochloric acid and determined spectrophotometrically with PAR. The various parameters like concentration of acid, equilibrium time, back eluting agents, loading capacity were optimized for quantitative adsorption of lead (II). The applicability of the proposed method was successfully applied to the analysis of diverse ions, binary mixture of associated metal ions, ternary mixtures, alloys, ayurvedic samples and water samples and lead (II) was determined with the PAR and results of analysis were confirmed by AAS.
