Abstract:

研究了磺胺甲恶唑(SMX)在11种土壤上的吸附行为.相关性分析表明,单一的土壤性质与表观吸附没有表现出明显的相关关系,SMX在土壤中的吸附可能受憎水性作用、阳离子交换、表面积等多个机理或因素的共同作用.进而研究了Ca2+、Mg2+、Zn2+3种金属离子与SMX在土壤中的共吸附.其中,Zn2+显著地促进了SMX的表观吸附,而Ca2+、Mg2+两种离子对SMX的吸附没有明显的影响.同时,SMX的存在也影响了3种离子的吸附行为,Ca2+和Mg2+的吸附降低,而Zn2+的吸附受SMX的影响不大.可能是由于Zn2+在土壤中是内界吸附,占据了内部的位点,取代了大量的H原子,使表面的负电荷减弱,降低了土壤与SMX的排斥作用,从而使其吸附增加.
