Application of Dispersive Liquid-Liquid Micro-extraction to GC-Determination of Residual Amounts of Pesticides

A review on the progress of application of dispersive liquid-liquid micro-extraction (DLLME) to gas chromatographic determination of residual amounts of pesticides was given in this paper, relating especially to the topics on the principle and procedure of extraction, the influential factors of extraction, including extraction solvent, dispersing agents, extraction time, values of pH and ionic strength (55 ref. cited).
