| 中文摘要: |
| 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 m 3 时 , 目标化合物的检出限为0.4 × 10 -3 μ g/m 3 ～ 6.0 × 10 -3 μ g/m 3 ; 当采样体积为6 m 3 时, 检出限为0.008 μ g/m 3 ～ 0.145 μ |
| 英文摘要: |
| The phthalate esters were detected by reversed phase HPLC in ambientairparticlescollected with superfine fiber membrane by self -made moderate flow equipmentsto capture semivolatile organic com pounds. The experimentalconditionsweretestedin method ofsamplepurity, distribution oftargetcompoundsin airphase and particles, and capture efficiency of sampler. The liner relation of method was good between0.50 mg/L and 50.0 mg/L. The limitdetection oftargetcompounds were from 0.4 × 10 -3 μ g/m 3 to 6.0 × 0 -3 μ g/m 3 assample concentration volume was1.0 mL atairsampling volume144 m 3 . Thelimitdetection of targetcompounds were from 0.008 μ g/m 3 to 0.145 μ g/m 3 asairsampling volume was6 m 3 . |
