Yc. Chan et al., USE OF A MODIFIED WALKLEY-BLACK METHOD TO DETERMINE THE ORGANIC AND ELEMENTAL CARBON CONTENT OF URBAN AEROSOLS COLLECTED ON GLASS-FIBER FILTERS, Chemosphere, 31(11-12), 1995, pp. 4403-4411
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 fib
re and teflon-backed glass fibre filters, The estimated accuracy of th
e 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 mu
g m(-3), 0.54 mu g m(-3) and 0.29 mu g m(-3).
