基于Walkley-Black方法的分析是一种快速而有效的方法，可以测定在玻璃纤维和聚四氟乙烯背衬玻璃纤维过滤器上采集的城市气溶胶样品的有机碳、元素碳和总有机碳含量。该方法对有机碳、有机碳和总有机碳的精密度分别为+18%、−33%和−8%，精密度分别为±7%、±21%和±4%，检出限分别为0.33μg m−3、0.54μg m−3和0.29μg m−3。
An analysis based on the Walkley-Black method is a rapid and effective means for determining the organic carbon, elemental carbon and total organic carbon content of urban aerosol samples collected on glass fibre and teflon-backed glass fibre filters. The estimated accuracy of the method is + 18%, −33% and −8% for OC, EC and TOC, respectively, the precision is ±7%, ±21% and ±4%, and the detection limit 0.33 μg m−3, 0.54 μg m−3and 0.29 μg m−3.
