An analytical method has been developed for the determination of phenol and bisphenol A in air. Air samples are concentrated on commercial silica by the well established tube-pump method. The trapped components are desorbed and analyzed by HPLC using UV detection at 275 nm. The method has been validated for a concentration range of 0.5-50 mg m-3 (based on a 10-l air sample) for both compounds. Linearity of response, adsorption/desorption efficiency, influence of humidity on sample collection and influence of temperature and time on storage of collected samples were studied. The reported technique provides a selective and sensitive method for environmental monitoring in industrial atmospheres as well as for personnel exposure measurement.
已开发出一种用于测定空气中苯酚和双酚A的分析方法。空气样品通过成熟的管泵法在商用硅胶上进行浓缩。捕集到的成分通过高效液相色谱法在275nm处进行紫外检测来解吸和分析。该方法已针对两种化合物在0.5 - 50mg m-3的浓度范围内（基于10升空气样品）进行了验证。研究了响应线性、吸附/解吸效率、湿度对样品采集的影响以及温度和时间对采集样品储存的影响。所报道的技术为工业大气中的环境监测以及人员暴露测量提供了一种选择性和灵敏的方法。
