Abstract：The adsorption-desorption characteristics of fluazinam in three types of soil, including yellow soil from Nanjing, red soil from Jiangxi and black soil from Northeast China, were investigated using batch equilibration experiments. The results indicated the adsorption-desorption isotherms of fluazinam in three different soils fairly fitted the Freundlich model at 25℃ with the adsorption constants of 119.34, 202.23, 311.88, respectively, which showed good correlations with organic matter (OM), cation exchange capacity (CEC) and clay content of the soils with the correlation coefficient being 0.9973, 0.9690, 0.8586. The variation of free energy of sorption was less than 40 KJ/mol, suggesting that the adsorption type belonged to the physical adsorption. And the column leaching results of fluazinam demonstrated that fluaziam was hard to leach in three types of soils.
