Selected three soil (yellow cinnamon soil, manual loessial soil and aeolian sandy soil) to study the kinetics and isotherms sorption of V(Ⅴ), and further explore the differences in the adsorption mechanism caused by initial V (V) concentration, ionic strength (IS), pH and different reaction times. It was observed that V(Ⅴ) adsorption onto the soil had three processes and completed rapid adsorption in 60, 100 and 120 min. The maximum adsorbing capacity of V(Ⅴ) on yellow cinnamon soil, manual loessial soil and aeolian sandy soil reached stable in pH range from 4 to 8. The adsorption capacity decreased with the increase of IS. V(Ⅴ) adsorption onto soil varied greatly with mineralogy and properties of soil, the surface area, soil organic carbon content and composition of particulate matter. This research enhanced the understanding of how soil properties affect vanadium (V) sorption onto agricultural soil.To investigate the reaction mechanism between vanadium (Ⅴ) and soil, and further explore the differences in the adsorption mechanism caused by initial V(V) concentration, ionic strength, pH and different reaction times. Selected three soil (yellow cinnamon soil, manual loessial soil and aeolian sandy soil) which are the typical agricultural soil from Shaanxi province to study the kinetics and isotherms sorption of V(Ⅴ). SEM study is used to probe the morphological features of the soil in the presence of vanadium and to investigate the change of surface functional groups on the three soils after adsorption by the FTIR spectra. It was observed that V(Ⅴ) adsorption onto the soil had three processes and completed rapid adsorption in 60 min, 100 min and 120 min. The maximum adsorption concentration of V(Ⅴ) derived from experimental data for the yellow cinnamon soil, manual loessial soil and aeolian sandy soil were 1124.6mg kg, 854.4mg kg and 748.6mg kg, respectively. The maximum adsorbing capacity of V(Ⅴ) on yellow cinnamon soil, manual loessial soil and aeolian sandy soil reached stable in the pH range from 4.0 to 8.0. The adsorption capacity decreased with the increase of ionic strength. V(Ⅴ) adsorption onto soil varied greatly with mineralogy and physical–chemical properties of soil, the BET surface area, soil organic carbon content and composition of particulate matter. This research enhanced the understanding of how soil properties affect vanadium (V) sorption onto agricultural soil.

选择三种土壤（黄肉桂土壤，人工黄土土壤和风沙质土壤）研究V（Ⅴ）的动力学和等温线吸附，并进一步探讨由初始V（V）浓度，离子强度引起的吸附机理的差异（ IS），pH和不同的反应时间。观察到V（Ⅴ）在土壤上的吸附经历了三个过程，并在60、100和120min内完成了快速吸附。V（Ⅴ）在黄肉桂土壤，人工黄土和风沙质土壤上的最大吸附能力在4〜8的pH范围内达到稳定。吸附能力随IS的增加而降低。V（Ⅴ）在土壤上的吸附随矿物学和土壤性质，表面积，土壤有机碳含量和颗粒物组成的不同而有很大差异。这项研究增进了人们对土壤特性如何影响钒在农业土壤上的吸附的认识。研究钒（Ⅴ）与土壤之间的反应机理，并进一步探讨初始V（V）浓度引起的吸附机理的差异，离子强度，pH和不同的反应时间。选取了陕西省的典型农业土壤三种土壤（黄肉桂土壤，人工黄土土壤和风沙土），研究了V（Ⅴ）的动力学和等温线吸附。SEM研究用于探测钒存在下土壤的形态特征，并通过FTIR光谱研究吸附后三种土壤上的表面官能团的变化。结果表明，V（Ⅴ）在土壤上的吸附过程分为三个过程，分别在60min，100min和120min内完成快速吸附。从实验数据中得出的黄肉桂土壤，人工黄土土壤和风沙质土壤的V（Ⅴ）最高吸附浓度分别为1124.6mg kg，854.4mg kg和748.6mg kg。在4.0至8.0的pH范围内，黄肉桂土壤，人工黄土和风沙质土壤对V（Ⅴ）的最大吸附量稳定。吸附能力随离子强度的增加而降低。V（Ⅴ）在土壤上的吸附随土壤的矿物学和理化性质，BET表面积，土壤有机碳含量和颗粒物组成变化很大。
