Bensulfuron-methyl(BSM) is a kind of highly efficient sulfonylurea herbicides.It's residue would do harm to following crops and bring serious pollution to environment and ecological toxicity.So it is important to study the method of analysing the residue of BSM in soil.Therefore,the pick-up of BSM in soil with supercriticai CO_2 extraction was systematically investigated in this paper.The main results were summarized as follows:
1 The measuration of equilibrium solubility of BSM in the supercr...
