Abstract:

采用OECDguideline106批平衡吸附解吸试验方法研究了环丙沙星在潮土0~20cm和20~40cm两个垂直土层中的吸附-解吸行为.结果表明,环丙沙星在潮土中的吸附和解吸过程均分为快速反应和慢速平衡两个阶段,且经过24h达到吸附和解吸平衡.准二级动力学方程能较好地拟合吸附和解吸过程,吸附速率常数为0.571kg·min-1·mg-1.两个潮土层对环丙沙星的吸附和解吸均不同程度地偏离线性模型,采用Freundlich方程可以对吸附和解吸数据进行良好的非线性拟合(P<0.01),吸附容量分别为672.977和693.426,其吸附等温线属于"S"型等温线.环丙沙星在两个潮土层中吸附以物理吸附为主.在解吸的过程中存在滞后现象,且解吸滞后系数均随着初始浓度的增加而增大,0~20cm土层的解吸滞后系数均大于20~40cm土层.在pH值为4~9条件下,环丙沙星的吸附参数lgKd值随pH的增加先增加后降低,当pH值为5时,吸附效果最好,0~20cm土层lgKd值为3.36,20~40cm土层lgKd值为3.90.阳离子吸附可能是潮土对环丙沙星吸附的主要机制之一.
