ACCELERATED SOLVENT EXTRACTION OF THE LIPID FRAC-TION FROM BIOTA

M.M. SKRYNNYK, M.V. MILYUKIN

Accelerated Solvent Extraction (ASE) has been investigated for the influence of dif-ferent factors such as temperature, volume of solvent, rate of solvent passage on recovery of hydropho-bic organic compounds from biota by different solvent and their mixtures. Basing on process optimization we developed, approbated and used express procedure for extraction of organic compounds from fish muscles tissue (10 min). This procedure recovers 85‒90 % of organochlorine pesticides (OCPs) and pol-ychlorinated biphenyls (PCBs) from fish muscles tissue. In this case water and water-soluble compounds are not present in the extract. This procedure does not require expensive equipment, and can be used for OCPs and PCBs monitoring in biota samples and solving other practical tasks.
