摘要

用玻璃纤维滤纸采集工作场所空气中的草铵膦,经Metrosep A Supp 5-150型阴离子色谱柱分离,以1.92 mmol/L碳酸钠-0.60 mmol/L碳酸氢钠混合溶液为流动相,用离子色谱法测定.该方法在0 mg/L～1.04 mg/L范围内线性良好,方法检出限为0.012 mg/L,按采集30 L空气计算,最低检出值为0.004 mg/m3.空白玻璃纤维滤纸的加标回收率为93.7％～102％,标准溶液6次测定结果的RSD为0.8％～4.3％.

Abstract

Glufosinate in the air of workplace was collected by glass fiber filter paper,separated by Metrosep A Supp 5-150 anion chromatographic column and determined by ion chromatography,with 1.92 mmol/L sodium carbonate-0.60 mmol/L sodium bicarbonate mixed solution as mobile phase.The method had a good lin-earity in the range of 0 mg/L～1.04 mg/L.The method detection limit was 0.012 mg/L.The minimum detecta-ble limit was 0.004 mg/m3 when the collection volume was 30 L.The recoveries of spiked blank samples in glass fiber filter paper were from 93.7％to 102％,and the RSDs of six measurements of the standard solutions were from 0.8％ to 4.3％.
