气相色谱法测定多泥沙水体中挥发性卤代烃
GAS CHROMATOGRAPHIC DETERMINATION OF VOLATILE HALOGEN SUBSTITUTED HYDROCARBONS IN SILTY WATER
摘 要
应用气相色谱-电子捕获检测器(ECD)检测法测定了多泥沙的黄河水样中挥发性卤代烃.用吹扫捕集法作试样预处理.为降低卤代烃在水溶液中的溶解度,采用了饱和氯化钠溶液作为专用电解质,因而也提高了方法的灵敏度,按优化的分析条件，对4种卤代烃作了试验.结果表明,四者分离良好,检出限在0.01~0.20 μg·L-1之间.加标回收率在95.0%~103.0%之间.

Abstract
Gas chromatography with ECD was applied to the determination of volatile halogen substituted hydrocarbons in silty water samples of the Yellow River.Puffing and trapping technique was used in the sample pretreatment.Saturated solution of sodium chloride was chosen as dectrolyte in the determination to lower the solubility of the halogen substituted hydrocarbons and hence to raise the sensitivity of the determination.Under the optimized condition of the method proposed,4 halogenohydrocarbons were satisfactorily separated and the detection limit obtained were in the range of 0.01-0.20 μg·L-1.Results of recovery test found were in the range of 95.0%-103.0%.
