摘要
介绍了一种用于 TEA挂片测定 NO2 的滤膜制备方法 ,解决了原方法中存在的滤膜空白值偏高且不稳定的问题。实验结果表明 ,该方法可用于大面积、多点位同步监侧中大批量滤膜的制备。
This paper introduced a method ,that is how to prepare trimethanolamine (TEA)handing filter for determination of NO 2 in air It solved the problem of the higher and unsteady blank in privious method It's proved by the experiment that this method could be used for the batch preparation of filter in synchronous monitoring with many sampling points in a great area
