摘要：
Adsorption of metsulfuron-methyl by kaolinite, goethite, amorphous alumina and the effects of urea on the adsorption were examined with equilibrium adsorption method. Results indicated that the adsorption was in accordance with Langmuir equation, with the maximum absorbing capacities ranking as amorphous alumina (2150 mu g.g(-1)), goethite (729.4 mu g.g(-1)) kaolinite (529.1 mu g.g(-1)). When urea was used in the adsorption system, the absorbing capacities of goethite and amorphous alumina to metsulfuron-methyl decreased whatever the addition order of urea and metsulfuron-methyl was. However, when urea was added before or simultaneously with metsulfuron-methyl in suspension of kaolinite, the adsorption quantity of metsulfuron-methyl was increased.
