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

The effect of soluble soil organic matter (SOM) on the adsorption of simazine in Hanford sandy loam was studied in batch, miscible displacement, and solubility experiments. Batch equilibrium data conformed to the linear adsorption model and indicated no effect on adsorption from the presence of SOM...

Description
Summary:The effect of soluble soil organic matter (SOM) on the adsorption of simazine in Hanford sandy loam was studied in batch, miscible displacement, and solubility experiments. 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. No substantial effect on breakthrough curve-fitted linear distribution coefficients or simazine water solubility was noted for SOM concentrations up to about 80 and 100 ppm organic C, respectively.
