Development Of Hybrid Polymeric/ Inorganic Ion Exchanger: Preparation, Characterization, And Environmental Applications, Surapol Padungthon

Theses and Dissertations

The study involves the development of two environmental applications using hybrid polymeric/ inorganic ion exchangers. First, the hybrid polymeric ion exchangers supported hydrated zirconium oxide (HZO) nanoparticles, referred to as HIX-Zr were developed for selective removal of heavy metals and anionic ligands. Second, salt-free water softening processes were presented using three different heterogeneous cation exchanger resins along with novel regeneration schemes. The HIX-Zr nanosorbents have been prepared, characterized, and extensively studied in relation to heavy metal (i.e., zinc) and anionic ligand (i.e., arsenate and fluoride) removal in fixed-bed processes at trace concentrations with the presence of high concentrations ...
