Abstract:

      In this paper£¬several extraction methods of organochlorine pesticides£¨OCPs£©£¬including homogenization£¬solid phase extraction£¬solid phase miroextraction£¬accelerated solvent extraction£¬pressured fluid extraction£¬supercritical fluid extraction£¬ultrasonic solvent extraction£¬soxhlet extraction£¬microwave assisted extraction£¬liquid-liquid extraction and matrix solid phase disperse£¬were introduced and classfied based on the properties of the matrixes.The advantages and disadvantages of those techniques were analyzed and compared.The development trends of extraction methods for OCPs were prospected.
