摘　　要：本文建立了活性炭管吸附CS2解析气相色谱法测定车间空气中微量O，O-二乙基硫代磷酰氯含量的方法，柱温1400c、汽化室温度为250℃、检测器温度250℃，氮气流量为50mL/min，用150mg活性炭管，采样流速为100-200mL／min时，其吸收效率为100％，解析效率为92．5％。方法的相对标准偏差小于10％（n=5），方法检出限为0．3mg／m^3。In this paper, a method of GC with active carbon for adsorption and CS2 for desorption was developed to determine the trace content of O,O-diethyl thiophosphoryl chloride in the air of workplace. The operation parameters were as following： column temperature 140℃ ,vaporizer temperature 250℃, the detector temperature 250℃ and the nitrogen flow rate 50 mL/min. When adopt 150 mg sized active carbon tube with sampling flow rate of 100 - 200 mL/min, the adsorption rate and desorption rate were 92. 5% and 100% respectively. The relative standard deviation and detection limit of the method were less than 10% （ n = 5 ） and 0. 3 mg/m^3 respectively.
