Abstract

The relative adsorption of trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine), triallate [S-(2,3,3-trichloroallyl)-diisopropylthiocarbamate], and diallate [S-(2,3-dichloroallyl)diisopropylthiocarbamate] was studied on several adsorptive surfaces. The herbicides were strongly adsorbed, with the following general trend: activated charcoal > peat moss > wheat straw (Triticum aestivum L.) ∼ cellulose triacetate > cation exchange resin > anion exchange resin > silica gel ∼ cellulose powder > kaolinite ∼ montmorillonite. Trifluralin and triallate were readily desorbed from montmorillonite by water, with miniminal desorption for peat moss, cellulose triacetate, and wheat straw.
