Abstract
A micellar-based preconcentration method for the extraction of Phenosafranine (PS) dye was developed by using adsorptive micellar flocculation (AMF) and cloud point extraction (CPE) techniques. In the case of AMF, aluminum sulphate (flocculant) and sodium dodecyl sulphate (SDS) were taken in 1:2 ratios for the extraction of PS dye. The parameters affecting the AMF and CPE were optimized. The calibration range and detection limits were 0.0-8.07 g/mL and 4.182 g/mL respectively for AMF. The calibration range and detection limits were 0.0-9.684 g/mL and 2.272ng/mL respectively for CPE.s The methods presented were used to extract PS dye from aqueous samples.
