Anionic resins preparation by sulfonation of waste polystyrene and studying the products obtained

One of the ways of polymer waste management is its chemical modification. Waste polystyrene (EPS) and virgin polystyrene (VPS) as a reference material were converted into polymeric flocculants by chemical reactions. The possibility of using waste polystyrene to remove the hardness of water has been investigated. Waste of polystyrene is consisting of white coffee cups, foam and they were converted into adsorbent by heterogeneous sulfonation. Infra red technique (FT-IR) has been used to confirm the sulfonation. Degree of sulfonation and cation exchange capacity has been determined by titration.
