Article Synopsis
- Pristine microporous organic polymers (p-MOP) are effective for sensing and adsorbing heavy metal ions, specifically mercury, due to their unique structural properties and the integration of heteroatoms.
- The study introduces a new hybrid material made from trimesic acid and phenylene diamine-based p-MOP combined with cellulose nanofibers from rice straw, exhibiting high porosity and excellent crystallinity for selective detection of Hg(II) ions in water.
- Characterized by various analytical techniques, the hybrid demonstrates a high adsorption capacity, effective kinetic and thermodynamic properties, and maintains 97% efficiency in removing mercury after multiple uses, showing promise for wastewater treatment applications.
Besides presence of heavy metals, especially arsenic in water bodies, northern India is striving to obliterate crop residue, which is otherwise burnt to make the fields ready for subsequent crop, causing acute air pollution. Through this study, an effort has been made to utilize wheat-straw cellulose to develop inexpensive and efficacious sensing cum annihilation system for deleterious arsenite ions As(III) in water by grafting a novel fluorophore, 3-bromofluoranthene on cellulose (BF@CFs). BF@CFs were characterized for structural, morphological and thermal properties using FTIR, XRD, TGA, FESEM, EDS and TEM, which confirmed the successful insertion of fluoranthene molecule on cellulose while preserving its crystalline nanofibrous structure.
