Heavy metal ions are a common water pollutant from industrialized areas and extraction is one of the most popular methods to remove the target analytes. However, extraction and determination of metal ions in water are often very difficult to perform due to their solubility in water. In order to resolve some of the issues in the extraction of trace metal ions from aqueous samples, this study explores newly prepared polyelectrolyte films coated on cellulose acetate membrane as extracting phase. Optimization coating materials showed that gelatin-alginate coated cellulose acetate membrane have the best performance to adsorb metal ions from water. The results open a possibility of the method to be successfully applied as extracting phase to adsorb and enrich heavy metal ions from aqueous matrices.
