Abstract

The aim of this study is extraction, preconcentration and spectrophotometric determination of Rhodamine B (RhB) in aqueous media by developing cloud point extraction CPE) methods and magnatic solid phase extraction (MSPE). The method includes extraction of the Rhodamine B (RhB) by CPE using a non-ionic surfactant Triton X-114; then stearic acid modified Fe3O4 magnetic nanoparticles (MNPs) are used to retrieve the micellar phase. Parameters of CPE and MSPE which effected quantitative extractions were investigated and optimized. the method was linear in the range from 10 to100 μg Kg-1 with the correlation coefficient (R2) of 0.9861 and detection limit of 9.952 ng g-1.
