Synthesis, characterization and applications of polymethylmethacrylate grafted psyllium as flocculant

- Psy-g-PMMA was synthesized by 'microwave assisted method'.
- FTIR spectroscopy provided experimental proof of the proposed mechanism of synthesis.
- Synthesized grades were studied for efficacy as flocculant for kaolin suspension.
- Psy-g-PMMA showed higher flocculation efficacy than psyllium.
- Higher the percentage grafting of Psy-g-PMMA, higher is its flocculation efficacy.
