AN ENVIRONMENTALLY FRIENDLY METHOD FOR EXTRACTION OF PARABENS IN VARIOUS SAMPLES USING LOW VISCOSITY AND LOW CLOUD POINT TEMPERATURE SURFACTANT

Abstract

Cloud point extraction is developed using a low viscosity surfactant (Sylgard 309) coupled with HPLC-UV. It is a simple method for extraction of parabens in various samples. At the optimum conditions, the method developed achieves limit of detection and extraction recoveries in the range of 0.01 ppm – 0.02 ppm and 68.5% -119.3%, respectively. Linearity of the calibration curves in the range of 0.2-1.0 mg/L. The correlation coefficient are achieved between 0.9995-0.9999. Each replicated samples are spiked with 1 mg/L of parabens. The results indicate that surfactant Sylgard 309 has a great potential for the extraction of organic pollutant in various samples.
