A rapid, highly sensitive modified polarographic method for the determination of styrene microconcentrations in air -0,5-I mg/cm3 was elaborated, on the different electrolyte of propionic acid or in 10-20 times higher sensitivity than the methods known so far; the relative error determination +/- 2%. The method is selective for styrene - aliphatic, aromatic and halohydrocarbons, aldehydes, ketones, esters do not interfere with the determination. Air samples are collected in 4-6 minutes, the polarographic analysis performed within 1-2 minutes. The implementation of the method is widely recommended for the improvement of the quality and effectiveness of sanitarychemical and hygienic control.
阐述了一种快速、高灵敏度的改良极谱法，用于测定空气中0.5 - 1毫克/立方厘米的苯乙烯微量浓度，该方法采用丙酸作为不同电解质，灵敏度比目前已知方法高10 - 20倍；相对误差测定为±2%。该方法对苯乙烯具有选择性——脂肪烃、芳烃和卤代烃、醛、酮、酯不干扰测定。空气样品在4 - 6分钟内采集，极谱分析在1 - 2分钟内完成。广泛推荐采用该方法来提高卫生化学和卫生控制的质量与效率。
