Abstract: Anovel procedure using Na2SO4 homogenization,HAc-HClO4 digestion followed by concentrated sulfuric acid and florisil column cleaning for pretreatment of biological samples in determination of trace organic chlorine compouds was developed. In combination with an open tubular glass capillary column gas chromatography it can be used to determine various organic chlorine compounds in biological samples rapidly, sensitively and accurately with detection limits in the range of sub-ppt to ppb and recoveries over 80%.
