采用气袋采样,气相色谱法分析了固定污染源废气中的14种挥发性卤代烃,各组分的曲线相关系数均大于0.99,方法检出限为0.0003~0.6 mg/m3;采用本方法对钢铁、石油化工厂和汽修厂等多家企业进行实样测试,各行业的加标样品相对标准偏差1.2%~8.8%,加标回收率为74.3%~116%.本方法的各项特性指标均达到预期要求,为分析固定污染源废气中的挥发性卤代烃提供了更为直接有效的方法.
DETERMINATION OF 14 KINDS OF VOLATILE HALOGENATED HYDROCARBONS IN EX-HAUST GAS BY GAS CHROMATOGRAPHY
In this paper,14 kinds of volatile haloge-nated hydrocarbons in the exhaust gas of stationary sources were analyzed by gas chromatography and air bag sampling.The curve correlation coefficient of each component was greater than 0.99;the detection limits of the method were from 0.0003 mg/m3 to 0.6 mg/m3.This method was adopted to test the real samples from iron and steel enterprises,petrochemical plants and auto repair factories.The relative standard deviation of spiked samples in various industries were from 1.2%to 8.8%and the recoveries were from 74.3%to 116%.All the characteristic indexes of this method can meet the expected requirements.This provides a more direct and effective method for the analysis of volatile halo-genated hydrocarbons in the exhaust gas of stationary sources.
