Use of a modified walkley-black method to determine the organic and elemental carbon content of urban aerosols collected on glass fibre filters

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%, −...

Description
Summary: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 −3 and 0.29 μg m −3.
