[Adsorption behaviors of herbicide glyphoste on soils].
The adsorption behaviors of herbicide glyphoste on three soils were studied. The influence of pH value and ion strength on adsorption was discussed. It was shown that the adsorption dynamic process of glyphoste on three soils all was first order reaction, and the adsorption isotherms all were linear, adsorption coefficients Kd ranged from 2.2207-3.5280 mL x g(-1). The adsorption percentage of glyphoste on three soils increased with the ionic strength decrease. The adsorption percentage of glyphoste on the Huhhot soil and Dongsheng soil increased with pH value gradually decrease (9-3), and the adsorption percentage of the Hangjing 2 soil early increased and late decreased with pH value gradually decrease (9-3).
