摘要
研究了(纳氏试剂比色法和次氯酸钠—水杨酸分光光度法)在室内空气监测中存在的问题,得出次氯酸钠—水杨酸分光光度法不适合于装修后有机物含量较高的室内空气监测的结论。同时,针对纳氏试剂比色法分别进行了不同采样时间、不同采样流量以及不同吸收瓶等条件下室内空气中氨的监测技术的研究,确定了室内空气中氨的最佳监测条件。
The text discusses some problems in the metrical methods (Nashi Reagent colorimetry and the method of sodium hypo chloritesalicin spectrophotometer) of the ammonia in indoor air contaminations by our mensurating the indoor ammonia in half year after fitment. We got the conclusion that the method of sodium hypo chloritesalicin spectrophotometer misfit the mensuration when there is much Carbohydrate in rooms after fitment. At one time, we determine the ammonia in indoor air in Nashi Reagent colorimetry in different time and different sampling flux and different absorb bottle and so on, and get the best metrical condition that mensurate the ammonia in indoor air.
