& In the present work, an efficient method based on ultrasound-assisted emulsification microextraction was developed for the determination of sodium benzoate (SB), p-hydroxybenzoic acid (PHBA), methyl-paraben (MP), ethyl-paraben (EP), and propyl-paraben (PP) in different samples. In this procedure, 40 lL of (5% w=v) aliquot 336 in 1-octanol was injected slowly into a 12-mL home-designed centrifuge glass vial containing an aqueous sample of the analytes that was located inside the ultrasonic water bath. The formed emulsion was centrifuged and the separated organic solvent was then injected into a 20-lL loop of high performance liquid chromatography coupled with UV detector. Under the optimum conditions, preconcentration factors (PFs) in the range of 109-490 were obtained. The performance of the proposed method was studied in terms of its linear range (LR, 0.6 lg=L up to 10000 lg=L), linearity (R 2 ! 0.9963), precision [RSD% 3.6; reproducibility, RSD (%) 9.8] and extraction recoveries (22.6-102.1%). Limits of detections (LODs) were 8.3, 1.2, 0.60, 0.42, and 0.25 lg=L for SB, PHBA, MP, EP, and PP, respectively. Finally, the applicability of the proposed method was evaluated by the extraction and determination of the target analytes from beverages, cosmetics, and water samples.

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.Keywords: cloud point extraction, parabens, sylgard 309, simple method for extraction Abstrak Pengekstrakan titik awan dibangunkan menggunakan surfaktan yang mempunyai kelikatan yang rendah (Sylgard 309) digabungkan dengan KCPT-UV.

A single-drop microextraction (SDME) method followed by in-syringe derivatization and GC-MS determination has been developed for analysis of five parabens, including methyl, ethyl, isopropyl, n-propyl and n-butyl paraben in water samples and cosmetic products. N,O-Bis(trimethylsilyl)acetamide (BSA) was used as derivatization reagent. Derivatization reaction was performed inside the syringe barrel using 0.4 microL of BSA. Parameters that affect the derivatization yield such as temperature and time of the reaction were studied. In addition, experimental SDME parameters such as selection of organic solvent, addition of salt, extraction time and extraction temperature were investigated and optimized. The RSD of the method for aqueous samples varied from 8.1 to 13%. The LODs ranged from 0.001 (n-butyl paraben) to 0.015 (methyl paraben) microg/L, and the enrichment factors were between 23 and 150.
