Abstract

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 ᷥ, Ჱ% and ᴥ, and the detection limit 0.33 姠m-3, 0.54 姠m-3 and 0.29 姠m-3.
