摘要
探讨用简易顶空装置预处理水样中苯及其同系物的条件，并优化色谱分离参数，从而改进了同时测定水体中痕量苯及其同系物的气相色谱方法。五种物质的标准土作曲线线性相关系数0．9967—0．9999，检测限0．004—0．080μg／L，平均回收率介于83．8％～112．4％，RSD（n=5）在4．7％～8．1％。
An improved method has been put forward to determine benzene and its analogies in water by static headspace gas chromatograph. The conditions for the head - space pretreatment and the parameters of gas chromatographie analysis have been optimized. Good results have been found for the determination of five analytes in real aqueous samples： correlation coefficients of external calibration curve are ranged from 0.9967 - 0.9999, detection limit （μg/mL） 0.004 ～ 0.080, average recoveries 83.8 % ～ 112 .4%, RSD （ n = 5 ） ： 4.7 % ～ 8.1%.
