Abstract

OBJECTIVES: Aluminum (AI) is a toxic metal at high levels and has been involved as a causative factor in several diseases, therefore, its determination in different samples is very important. METHODS: In this study a method based on CLOUD POINT EXTRACTION (CPE) technique in mixed micellar medium was applied for the extraction and preconcenttation of Al in different samples. For the CPE of Al, an aliquot of 25 ml solution containing appropriate amounts of Al, acetate buffer, morin and surfactant (Tttiton X-114 + SDSN) were kept in the thermostatic bath at 50ºC. Thus, two phases were appeared and separation of these phases was achieved by centrifugation. After cooling in ice-bath the surfactant-rich phase became viscous and the upper aqueous phase decanted. The fluorescence intensity of chelate in the micellar phase (after addition of 2.5 ml of ethanol-water mixture) was measured at 512 nm with the excitation set at 442 nm. RESULTS: The parameters affecting complication and phase separation were studied and optimized. Under the optimum experimental conditions, the detection limit of Al for the preconcenttation of 25 ml of solution was 0.52 µg 1-1 . The calibration graph was linear within a range of 2-200µg 1-1 AI. The relative standard deviation (RSD) of 5 replicated determinations of 10 µg 1-1 of AI was 2.1%. CONCLUSION: The method was successfully applied to the determination of Al in water samples and PARENTERAL SOLUTIONS.
