Preconcentration and spectrophotometric determination of Fe(III) by cloud point extraction using Zincon as complexing agent

A cloud point extraction (CPE) process was described for the separation and spectrophotometric analysis of Fe(III) in different water samples blood as chelating agent. The complexation reaction between Zincon elaborated at pH 5.0 using acetate buffer complex quantitatively recovered a mixed micelle system composed cethyltri methyl ammonium bromide (CTAB) Triton X-114. This carried out room temperature presence 0.05 mol L-1 Na2SO4 salting-out electrolyte. linearity up to 1000 µg L-1. preconcentration factor 50. precision (as relative standard deviation) limit detection were 2.5% 3.1 L-1, respectively. proposed procedure used data statistically comparable those achieved ICP-OES technique.
