Abstract

Dissolved organic material in filtered urban runoff samples was fractionated by gel filtration chromatography. Two distinct organic fractions were isolated on a column of Sephadex G25, with K_D value ranges of 0.1–0.3 and 0.5–0.9. The first fraction tended towards a “first flush” on the stormwater hydrograph, while the second fraction was characterised by a late loading and no evidence of exhaustion. Both fractions had Cu complexation properties. Fraction 1 showed the greatest degree of Cu complexation with a total capacity of 49.5 mM (g organic C)⁻¹.
