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.

Abstrak

Pengekstrakan titik awan dibangunkan menggunakan surfaktan yang mempunyai kelikatan yang rendah (Sylgard 309) digabungkan dengan KCPT-UV. Ini merupakan satu kaedah yang mudah untuk pemisahan paraben dalam pelbagai jenis sampel. Pada keadaan yang optimum, kaedah yang dibangunkan ini boleh mencapai had pengesanan dan perolehan semula pengekstrakan dalam julat 0.01 ppm – 0.02 ppm dan 68.5% -119.3%. Pekali korelasi yang dicapai adalah dalam julat 0.9995-0.9999. Larutan piawai yang ditambahkan dalam sampel iaitu 1mg/l paraben dalam setiap sampel replikat. Keputusan kajian menunjukkan bahawa surfaktan Sylgard 309 mempunyai potensi yang besar untuk diterokai bagi pengekstrakan pencemar rganic dalam pelbagai sampel.
