【Abstract】 Pyridine in environmental sampls was separated and detected by NPD with GC and broad capillary column. The separation was sufficient and the peak was satisfied, and the detection was sensitive and had broad lineage with detection limit 0.004 mg/L. The determination is applicable to the analysis of environmental air and water quality.更多还原
