Cellulose Nanozyme Composites for the Remediation of Pharmaceutical Wastewater

Abstract

In this research, the synthesis and description of a cellulose nanocrystal (CNC) derived Zn0.5Mn0.5Fe₃O₄ composite will be sought in which the intended purpose will be to utilize the compound in the treatment of pharmaceutical wastewater. The rationale behind the use of the CNC is that it is biocompatible with high surface area and has the potential to provide a successful support structure of metal oxides. The compounds were found to be very effective in removing contaminants, which was enhanced by the addition of Fe3O4, Zn and Mn nanoparticles that enhanced the catalytic and adsorption characteristics of the compounds. It was determined, as a consequence of the experimental work, that the Zn0.5Mn0.5Fe₃O₄@CNC composite exhibited a good catalytic degradation of pharmaceutical contaminants and most particularly under varied pH condition and greatest activity at pH alkalinity. The effectiveness of the functionalization and stability of the composite structure in the degradation process was validated by the UV-vis analysis and FTIR analysis. The paper introduces the prospect of the Zn0.5Mn0.5Fe₃O₄@CNC composite as a new environmental friendly and a high promising material in the process of advanced wastewater treatment that will serve as a sustainable solution to the pharmaceutical pollution and will aid in preserving the environment and human health.
