摘要
目的研制测定空气中苯乙烯的被动式个体采样器。方法根据费克第一扩散定律设计新型被动式个体采样器,并对采样器的性能指标进行评价。结果在温度为10～40℃,相对湿度为40%～80%,风速为100～600cm/s的范围内,被动式采样器测定空气中苯乙烯的采样流量为61.8ml/min,吸附容量为5.95mg,最短采样时间为30min,用前稳定性≥30d,样品稳定性≥14d,精密度测定显示其相对标准偏差(RSD)为8.07%～9.37%。结论本实验研制的苯乙烯个体采样器可以做为一种测定空气中苯乙烯的新型采样仪器。
Objective To make a passive personal sampler for the determination of the styrene in the air. Methods To make a passive personal sampler for the determination of the styrene in the air. Results Under the condition of wind velocity of 100-600 cm/s, relative humidity of 40%-80% and temperature of 10-40 ℃, the sampling flux of the passive sampler was 61.8 ml/min, the capacity was 5.95 mg, the shortest sampling time was 30 min, the self life was at least 30 days, the storage stability was at least 14 days, the RSDs were 8.07%-9.37%. Conclusion This new kind of passive personal sampler can be used as a new device for the determination of the styrene in the air.
