Abstract
The sorption-desorption behavior of 2 4-dichlorophenoxyacetic acid 2 4-D was examined using 3 Malaysian soils that differ in their physical and chemical properties. Soil samples were equilibrated with either 0 0.25 0.5 1 2.5 5 7.5 10.00 or 15 ppm of 2 4-D for 24 hr in a centrifuge tube after which the sample was centrifuged at 3 500 rpm for 15 min. The concentration of 2 4-D was measured at 230 nm using Waters 717 HPLC equipped with Zorbax C18 column and a PDA detector. The results indicated that sorption of 2 4-D was highest in peat soil followed by Selangor and Rengam soils. Total carbon has positive significant correlation with both Kd and Kf. Desorption was highest with Rengam followed by Selangor and the lowest desorption was from peat. Low sorption of 2 4-D in Selangor and Rengam soils suggests that there is a possibility for the herbicide to be leached from the soil profile if applied at high rates.
