Crystal Violet Dye (CVD) is a toxic and persistent cationic dye that poses environmental risks. This study developed a Chitosan-PVA/Ag-CeO₂ composite via an environmentally friendly green synthesis using noni leaf extract (Morinda citrifolia L.). The composite was synthesized by coprecipitation, with chitosan and PVA as biopolymer matrices, Ag as a dopant to enhance photocatalytic and antibac…
This research aims to synthesize composite Fe3O4/kitosan-polivinil alcohol/TiO2 as an effort to overcome tetracycline waste which pollutes the environment. The magnetic nanoparticle material Fe3O4 acts as a magnetic material, chitosan-polyvinyl alcohol as a barrier between Fe3O4 and TiO2 to prevent dissolution effects which can reduce the effectiveness of degradation, and TiO2 is used as a cata…
