Abstract: | Statement of research work: The research work deals with the experimental investigation of adsorption of harmful dyes and chromium (VI) metal from synthesized wastewater by using phosphoric acid-activated carbons. These activated carbons were developed into inexpensive and effective adsorbents from biomass which is abundant in nature. Easily available plant materials with simple chemical activation were used to investigate the water treatment. The studies of adsorption efficiencies characterize these activated materials by Fourier transform infrared (FTIR), SEM, BET, and X-ray diffraction (XRD). The various adsorption of isotherms and kinetic models were used to interpret the experimental data. Further experiments were designed based on the preliminary studies using Central Composite Design (CCD) superimposed on Response Surface Methodology (RSM) using the best performing adsorbent in the study. Finally, the results were analyzed statistically, followed by isothermal and kinetic studies. This work has not been carried out and reported in the literature. newlineThe first chapter deals with the introduction, literature survey, and scope for the investigation. The second, third, fourth, fifth, and sixth chapter deal with the experimental information about the process of the adsorption plant Prosopis Cineraria bark Activated Carbon (PCAC), Ocimum Basilicum Seed Activated Carbon (OBAC), and Tecoma Stans Activated Carbon (TSAC) for the sorption of Methylene Blue (MB), Rhodamine B (RB), Rhodamine 6G (R6G), and hexavalent chromium (Cr (VI)). These adsorbents were activated by phosphoric acid and characterized by SEM-EDS, BET, FT-IR, and XRD analysis. newline |
