Summary. Measurements were made of the effect of exchangeable cations on the adsorption of linuron and atrazine by an ion‐exchange resin, cellulose phosphate powder, bentonite and a peat soil. The cations studied were Ca 2+ , Ni 2+ , Cu 2+ , Fe 3+ and Ce 4+ . The results with linuron were consistent with the hypothesis that complex formation with exchangeable cations is a possible mechanism of adsorption. This was not so with atrazine due to complications arising from pH effects, and it seems unlikely that adsorption of atrazine by this process is significant.
