Novel one-pot synthesis of dicarboxylic acids mediated alginate-zirconium biopolymeric complex for defluoridation of water

- An environmentally friendly approach for preparing Alg-Ox-Zr complex.
- Alg-Ox-Zr complex was prepared by the one-pot method.
- Maximum defluoridation capacity was observed at 20 min contact time.
- The fluoride removal was by ligand exchange mechanism.
