摘要：

In order to investigate the dynamic characteristics of biosorption materials, three biosorbents were selected in this work, and the terahertz spectroscopy characteristics of biosorbents were tested in different biosorption stages. Experiment results show the refractive indexes of the same biosorbent obviously change in different biosorption stages, and the refractive indexes of different biosorbents are different in the same biosorption stage. Research on the interaction between biosorbents and heavy metals provides abundant information on biosorption. Terahertz time-domain spectroscopy (THz-- TDS) can not only characterize the inherent features of biosorbents and the change in optical parameters in the biosorption process, but also be helpful to identify and control the biosorption process. © All right reserved.
