Effect of naturally occurring soluble organic matter on the adsorption and movement of simazine [2-chloro-4,6-bis(ethylamino)-s-triazine] in Hanford sandy loam

Abstract

A series of batch, miscible displacement, and solubility experiments were conducted to examine the effect of soluble soil organic matter (SOM) on the adsorption of simazine in Hanford sandy loam. Batch equilibrium data conformed to the linear adsorption model and indicated no effect on adsorption from the presence of SOM up to 45 ppm organic carbon over a simazine concentration range of 30-1900 mg/mL aqueous
