Abstract：The adsorption of olaquindox onto five soils including Northeast China black soil, Changshu paddy soil, Shanxi fluvo-aquic soil, Nanjing yellow brown soil, and Jiangxi red soil was investigated using batch equilibration technique and the factors governing the adsorption were investigated. The sorption of olaquindox could be well fitted by both the Langmuir and Freundlich isotherm for each type of the soils. Sorption distribution coefficients KF of five tested soils were 2.813, 1.740, 0.446, 0.309, and 0.201, respectively, suggesting that olaquindox is only slightly adsorbed on the soils. The values of KF wer well correlated to certain physical-chemical properties of the soils such as organic matter contents and cation exchange capacity. A poor relationship was found between KF and pH or clay contents of the soils. The sorption of olaquindox on the soils was also affected by temperature and ionic strength. Lower temperature and ionic strength favor to the sorption.
