Separation and preconcentration of heavy metals in environmental samples by nicotinium molybdophosphate resin.

Abstract

The purpose of this study was to measure absorption properties of nicotinium molybdophosphate and to test extraction and recovery procedures for different metal pollutants (e.g. Cd, Cr, Cu and Pb). Procedures have been tested for single metal pollutants and for complex synthetic mixtures of them. Furthermore the nicotinium molybdophosphate resin technique is extended to the analysis of environmental samples collected in different areas of Kampala City.
