Case Study of the Day: Molecular Sponge to Remove Pollutants from Water: IISER

About the Development

  • The presently used sorbent materials for water purification trap the pollutants through an ion-exchange strategy to purify water, but they suffer from poor kinetics and specificity.
  • The developed material named Viologen-unit grafted organic framework (iVOFm), employs an amalgamation of electrostatics-driven ion exchange combined with nanometer-sized macropores and specific binding sites for the targeted pollutants.
    • Ion Exchange (IX) is a process of deionisation where dissolved impurity ions in water are replaced by hydrogen and hydroxyl ions, purifying the water.
  • The size and number of tunable macropores, along with the strong electrostatic interaction of iVOFm can quickly remove various toxic pollutants from water.
  • The fast pollutant trapping capacity of the material is attributed to the faster diffusion of pollutants through the ordered interconnected presence of macropores in the material.
  • On the whole, this cationic compound is adaptable for sequestering various pollutants and is a possible solution to the water pollution problem.
