  • 摘要: 建立了大气颗粒物（PM2.5、PM10）中左旋葡聚糖、甘露聚糖、半乳聚糖的高效阴离子交换色谱（HPAEC）与脉冲安培检测器（PAD）联用（HPAEC-PAD）技术的快速检测法.样品采用超纯水30 min振荡提取，经浓度250 mmol·L-1，流速0.45 mL·min-1的氢氧化钠淋洗液洗脱，45 min完成检测，该方法线性良好，相关系数达0.9999，实际样品测试加标回收率在89%-104%，精密度在1.2%-7.1%.对北京市2016年1月采暖季的大气颗粒物样品（PM2.5、PM10）进行了检测，其中左旋葡聚糖浓度较高分别为113±100 ng·m-3，118 ±124 ng·m-3，计算左旋葡聚糖与甘露聚糖浓度比例关系可知，北京冬季大气颗粒物中生物质燃烧来源主要为硬木燃烧.
    Abstract: A rapid analytical method of Ion chromatography by coupling high performance anion exchange chromatography (HPAEC) with pulsed amperometric detector (PAD) for the determination of three dehydration glycans in atmospheric particles(PM2.5、PM10) was established. Samples were extracted by 45 min shaking in ultrapure water, and dehydration glycans were separated by sodium hydroxide with a concentration of 250 mmoL·L-1 and a flow rate of 0.45 mL·min-1. Correlation coefficients were 0.9999 for this method. The recovery was from 75% to 102%, and the precision from 1.2% to 7.1%. In heating season of Beijing in January 2016, atmospheric particulate matter (PM2.5, PM10) samples were analyzed. The concentration of Levoglucosan was the highest, which were 113±100 ng·m-3,118±124 ng·m-3 in PM2.5 and PM10 respectively. The proportion of Levoglucosan and mannan implies that hardwood burning is the main source of biomass combustion in Beijing.
