摘要：
We studied the interaction of the cationic pesticide chlordimeform with humic and fulvic acids from different soils. The mechanism of chlordimeform adsorption is essentially a cation exchange reaction. Adsorption is influenced by the origin of the humic substances because of the different content in functional groups. Fulvic acids adsorb in lower proportion than humic acids from the same soil, despite the higher content in functional groups. © 1990 Williams & Wilkins.
