炸药爆炸后有毒气体中氮氧化物快速吸收法的研究

Determination of Nitrogen Oxides in Poisonous Gases from Explosive Explosions Using the Rapid Absorption Method

本文论述了用加入过氧化氢、氧和氢氧化钠添加物,快速测定炸药爆炸后有毒气体中氮氧化物含量的比色分析方法。考察了氧气加入量、过氧化氢浓度、吸收液的pH值对氧化时间的影响。结果表明:本方法具有与空气氧化法一样高的准确度和灵敏度。氮氧化物的吸附仅仅在20分钟内完成。此法适用于快速测定有毒气体中氮氧化物含量。

Rapid determinating nitrogen oxides in poisonous gases from explosive explosions using Colorimetric analysis by adding oxygen, hydrogen peroxide and sodium hydroxide solution to sample gases has been carried out in this paper.The effects of additions' properties, such as oxygen volume, concentration of hydrogen peroxide, pH of absorption solution, on oxidation time have been described.The results shown that the method is characterized by high sensitivity and accuracy in the same way as air oxidation process.The absorption of nitrogen oxides finished within only 20 minutes.This method could be used to determine the concentrations of nitrogen oxides in poisonous gases.
