Description
A liquid-ion exchange membrane was developed for the separation and quantitative recovery of iron, as Fe3+ and other cations from natural waters under controlled pH conditions. The influence of pH of the aqueous sample on the extraction of eleven cations is illustrated. Quantitative extractions of Fe3+, Co2+ and Ca2+ at concentrations of 0.1-1.0 μg l-1 from aqueous solutions are demonstrated. The average recovery of Fe3+ under optimized conditions is 99.5% with a relative standard deviation of 1.7% (n=8). Ion concentrations are measured by atomic absorption spectrometry.
