Ion exchanger is widely used in various industries. The most common applications of ion exchange are water deionization or softening, metal recovery, production of ultra-pure water, and fuel cells. In this study, it was prepared for nanofiber with high impact polystyrene (HIPS) by electrospinning. HIPS nanofiber is able to crosslinking after electrospinning with crosslinking agent. After thermal crosslinking, HIPS nanofiber was sulfonated by sulfuric acid. It was investigated FT-IR, XPS, water uptake, ion exchange capacity (IEC), SEM, and contact angle. It analyzed XPS to confirm the elements of sulfonated HIPS surface. Under the optimized condition, it was observed adsorption properties for divalent metal ions such as Co2+, Cu2+. |
