摘要：

A considerable fraction of the refractory organic carbon in airborne particulate matter is to be attributed to humic-like substances (HULIS). Such atmospheric HULIS isolated from different air dust samples by a microscale extraction procedure were characterized by capillary electrophoresis (CE). For fractionation of HULIS the working conditions of the CE system were optimized using a berate buffer (pH 8.2), polyacrylamide (PAA) coated, fused-silica capillary and polyethylene glycol as sieving modifier. Using CE under optimized conditions, HULIS produced electropherograms showing well resolved and reproducible signals.
