氢氧化钠吸收—盐酸萘乙二胺分光光度法测定污染源废气中的氮氧化物

The Sodium Hydroxide Absorb-in Ambient air-Griess-Saltzman Method Determined Nitrogen Oxides in Exhaust of Pollutant Fountainhead

对非稳态工艺废气中氮氧化物的监测 ,目前的监测方法无法获得准确满意的结果 .氢氧化钠吸收—盐酸萘乙二胺分光光度法监测 ,可以延长采样时间 ,扩大测定范围 ,消除了推荐。

Now the monitoring method of nitrogen oxides in fitful process exhaust can't obtain satisfactional accurate outcome.The sodium hydroxide absorb-in ambient air-Griess-saltzman method not only extend time of sampling and expand testing limit,but also eliminate any defect in recommendable method.
