Abstract
By selection of a suitable wash solution pesticides can be separated from dissolved organic materials (DOM) by solid phase extraction (SPE). This allows the analysis of phenoxy acids and s-triazines by HPLC. DOM interferes with adsorption isotherms of atrazine and MCPA, in lake water and even after aluminum flocculation, AC filtration and ozone treatment. Possible mechanisms are competitive adsorption on AC, or complexation of the pesticides with DOM, or a combination of both. The adsorption of MCPA on AC is likely weaker than for atrazine, probably due to the charged chemical character of MCPA. The reduction of adsorption capacity of MCPA on AC in the presence of DOM is also greater than atrazine.
