摘要
制作了半挥发性有机物中流量采样装置,使用超细玻璃纤维滤膜采样,反相液相色谱法测定环境空气中酞酸酯类,并对样品净化方式、目标化合物在气相和颗粒物上的分布规律及采样器的捕集效率进行了试验。方法在0.50 mg/L^50.0 mg/L之间线性关系良好,当浓缩体积为1.0 mL、采样体积为144 m3时,目标化合物的检出限为0.4×10-3μg/m3~6.0×10-3μg/m3;当采样体积为6 m3时,检出限为0.008μg/m3~0.145μg/m3。
The phthalate esters were detected by reversed phase HPLC in ambient air particles collected with super fine fiber membrane by self-made moderate flow equipments to capture semi volatile organic compounds. The experimental conditions were tested in method of sample purity, distribution of target compounds in air phase and particles, and capture efficiency of sampler. The liner relation of method was good between 0.50 mg/L and 50.0 mg/L. The limit detection of target compounds were from 0.4 ×10^-3 μg/m^3 to 6. 0×10^-3 μg/m^3 as sample concentration volume was 1.0 mL at air sampling volume 144 m^3. The limit detection of target compounds were from 0. 008 μg/m^3 to 0. 145 μg/m^3 as air sampling volume was 6 m3.
