摘要
目的:研究经过硝酸浸泡的滤筒是否可以用来监测烟尘浓度,从而可以使用同一个滤筒同时测定烟尘和烟尘中的铅。方法:分别按照不同冷却时间和不同室内湿度下,对滤筒恒重情况的分析,从而得出所需的规律,并对实际样品进行了测定。结果:认为经过硝酸浸泡的玻璃纤维滤筒能更快的进入恒重状态,受空气湿度的影响较小。结论:可以使用同一个滤筒测定烟尘和烟尘中的铅。
Aim： To study the filter cylinder immersed by nitric acid can be used to monitor soot concentration or not, so can determine to use this filter cylinder to monitor soot concentration and plumbum together. Method Respectively according to different cooldown time and different indoor temperature. Results： It suggested the filter cylinder immersed by nitric acid cool down more fast and it was affected by humidity a little. Conclusion： It could monitor soot concentration and plumbum together.
