Synergetic photocatalytic and adsorptive removals of metanil yellow using TiO2/grass-derived cellulose/chitosan (TiO2/GC/CH) film composite

Chitosan (CH) and cellulose are the most abundant biopolymer which can be utilized for hazardous dye removal. By incorporating TiO2 onto cellulose/CH matrix, our research aims to achieved higher metanil yellow removal by means of synergetic adsorption/photodegradation mechanisms. The particles were extracted from wild grass (Imperata cylindrica L.) obtain grass-derived (GC). Simple blending method was used prepare TiO2/GC/CH, in composition determined simple additive weighting (SAW). TiO2/GC/CH characterized tensile strength test (also SAW), Fourier Transform-Infrared (FT-IR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), electron microscopy (SEM). Metanil using work best at acidic pH range. follows pseudo-second-order kinetic (R2 = 0.99699) Langmuir isotherm 0.99786) modellings. Higher qm obtained under UV irradiation (qm 171.5266) proves synergism between adsorption photodegradation.
