Abstract
A new cloud point extraction (CPE) procedure with spectrophotometry for the pre-concentration and determination of iron(II) has been developed. In this method, Fe2+ was complexed with 1,10-phenanthroline at a pH of 4.2. Fe2+-1,10-phenanthroline complex was then extracted into mixed micelles of Triton X–114 (TX–114) and docusate sodium salt (DOSS). Various parameters such as pH, concentration of 1,10-phenanthroline, concentrations of the surfactants (TX–114 and DOSS), concentration of salt (Na2SO4), equilibration temperature and equilibration time were optimized. Under optimum conditions the linear range of Fe2+ was found to be 0.14-2.23 μg mL–1. The corresponding detection limit was found to be 5.1 ng mL–1. The proposed method has been successfully applied to the determination of Fe2+ in tap water and sea water samples. The recoveries were found to be in the range of 80-95 % and the effect of sodium nitroprusside on the recovery was studied.
