中文摘要：

调查了在不同的pH、离子强度、胡敏酸和竞争性离子存在的条件下Sb（V）在高岭土表面的吸附行为.pH对Sb（V）在高岭土表面的吸附行为影响显著,pH在3~8之间时,随介质pH的升高,Sb（V）的吸附减弱;离子强度、胡敏酸的存在对吸附的影响均不显著;PO43-的存在对Sb（V）在高岭土表面的吸附有明显的抑制作用.

英文摘要：

Sb（V） adsorption on kaolinite and influence of chemical parameters such as pH,ionic strength,competitive ions and humic acid was examined.Data indicated that adsorption was affected strongly by pH.Sb（V） adsorption decreased with increasing pH from 3 to 8.Ionic strength and humic acid had no effect on adsorption.The presence of PO3-4 significantly inhibited Sb（V） adsorption on kaolinite.
