Preparation of hydrochar with high adsorption performance for methylene blue by co-hydrothermal carbonization of polyvinyl chloride and bamboo

Abstract In this work, jasmine flower derived activated carbon were successfully synthesized by hydrothermal carbonization process at the different annealing temperature. The Crystallinity, phase, structural, morphological and optical properties of activated carbon were investigated using X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), Transmission electron microscope (TEM), and UV-visible spectroscopy analysis. The graphitic phase of carbon was obtained from the XRD pattern. Surface morphology reveals irregular-shaped nanoparticles. The photodegradation of methylene blue (MB) was carried out under the visible light irradiation technique to study its photocatalytic activity. The activated carbon obtained at 400oC, 500oC and 600oC shows a photocatalytic degradation efficiency of 86%, 90%, and 94%, respectively. Antibacterial activity of activated carbon was examined against S. Aureus (MTCC-737) and E-Coli (MTCC- 443) microbial pathogens, and their potent antibacterial activity was examined from the zone of inhibition layer.

Kinetic And Thermodynamic Study

In present study, uniformed nanozirconia is obtained via precipitation, ball milling and spray drying. The characteristics of methylene blue adsorption by nanozirconia are studied in details. The morphology of nanozirconia is examined by SEM. The influence of temperature is studied to obtain the optimal adsorption conditions. The equilibrium adsorption isotherms and the kinetic properties of the adsorption process are investigated to study the mechanism. The thermodynamic properties of methylene blue adsorption is investigated, and the thermodynamic parameters of Gθ, Hθ and Sθ are calculated. The results show nanozirconia has high adsorption ability of 43.99 mg/g to methylene blue, and the adsorption reaction is a spontaneous and physic-sorption process.
