Journal of Chromatography A 736 (1-2) : 211-218. ScholarBank@NUS Repository. | Abstract: | C18-impregnated disks for solid-phase extraction were evaluated for the extraction of organochlorine pesticides (OCPs) from water samples, and stability of the pesticides in storage. Good recoveries from different water samples were obtained. Microwave-assisted solvent extraction (MASE) was employed for the extraction of marine sediments spiked with OCPs. Factors affecting the efficiency of MASE were also investigated. Recoveries of 17 OCPs and 2 OCP surrogates were in the range 70.6-93.1% with mean deviation between 2.0 to 8.0%. | Source Title: | Journal of Chromatography A | URI: | http://scholarbank.nus.edu.sg/handle/10635/93555 | ISSN: | 00219673 |
