摘    要:被动式联苯-联苯醚的监测器以酸及硝化混合液处理过的玻璃棉为吸收介质,被动式吸收气体DTA;并通过乙醚-丙酮比色,测定监测器所采集到的DTQ量,根据累积浓度与对应的采样量,建立它们之间的关系。所研究的监测器能准确测定1.5-21mg.h/m^3的DTA,重复性好,变异系数小于12%;且操作简单,具有良好的采样效率,变异系数小于5.5%,平均采样速度为141.17ml/min。

关 键 词:被动式监测器  环境监测  监测仪器  研制

Abstract:A passive personal diphenyl-diphenylether (DTA) dosimeter has been developed for determination of DTA in ambient air.The dosimeter consists of a capped glass tube packed with glass wool treated with nitrify mixture.The absorbed DTA was analyzed by ether-acetone colorimetric method and connected linear character of passive personal DTA dosimeter.The results indicated that the dosimeter is suitable over a range of DTA concentrations from 1.5 mg·h/m3 to 21 mg·h/m3.The reproducibility is good with a relative standard deviation of less than 12%.A sampling rate of 141.17 ml/min has been obtained and its relative standard deviation is less than 5.5%.
Keywords:passive dosimeter  DTA  accumulative concentrations  absorbed amount
