Abstract
A carboxymethyl cellulose hydrogel loaded with TiOnanoparticles for wastewater treatment is provided. The TiONPs@CMC hydrogel is made by a method including providing raw date fiber, bleaching the raw date fiber, delignifying the bleached raw date fiber, and then performing alkalization and etherification on the bleached raw date fiber to produce date derived CMC; followed by dissolving the CMC in calcium chloride to form a paste-like solution, adding TiONPs to the paste-like solution, and freeze-drying the paste-like solution to obtain the TiONPs@CMC hydrogel. The TiONPs@CMC hydrogel is effective for degrading pathogens contaminating wastewater and preventing biofilm formation in wastewater systems.
