ABSTRACT
This chapter explores the feasibility of using two novel morphologies of ion exchangers, composite ion exchange membranes and ion exchange fibers that can be used in such unfavorable conditions of solid-phase decontamination. It focuses on aspects of tailoring the chemistry within the sludge reactor to get optimum results. The chapter presents details of material characterization of and potential application scenarios for both composite ion-exchange material and ion exchange fiber (IXF). The chapter shows that the chelating functionality of the microspheres chosen is iminodiacetate. It identifies the suitability of using chelating ion exchangers but in two forms, composite membrane and IXF, such that they can be used in a reactor containing high concentrations of suspended solids. The composite membrane was found to be compatible with the sludge medium and durable in the sludge/slurry reactor environment over a large number of cycles.
