Dyes have mutagenic and carcinogenic nature, and their removal from the environment is necessary. In this study, different types of poly vinyl alcohol and alginate (PVA-Alg) biocomposite beads were synthesized and characterized for methylene blue (MB) removal from aqueous phase. Activated carbon (AC), Ferric Oxide (Fe3O4) nanoparticles and ionic liquid (IL) were impregnated in PVA-Alg composite for MB adsorption from aqueous solution. Synthesized beads were characterized using different analytical tools such as Fourier transform inferred (FTIR) and scanning electronic microscopy (SEM). Among the tested beads, the PVA-Alg beads impregnated with AC have higher adsorption efficiency for MB and therefore was selected for further study and their adsorption for MB was compared with membrane having same composition. Impact of various experimental factors such as pH of MB solution, adsorption dosage, contact time, MB solution concentration and temperature were studied. To know the mechanism of adsorption of MB on the synthesized beads, kinetics, isotherm and thermodynamic study were performed. MB adsorption on the beads followed pseudo-first order kinetic model. Isotherm study showed that MB adsorption on beads can be explained by both Freundlich and Langmuir adsorption isotherm. Adsorption capacity of beads for MB was 769.23 mg/g as calculated from the Langmuir isotherm. Thermodynamic study clearly showed that MB adsorption is spontaneous in nature. The overall results concluded that PVA-Alg beads impregnated with AC have higher potential for MB adsorption from aqueous phase.
