A Novel Bio-adsorbent of Mint Waste for Dyes Remediation in Aqueous Environments: Study and Modeling of Isotherms for Removal of Methylene Blue

The objective of this study was to investigate the possibility of using mint waste as a bioadsorbent for the removal of dye (Methylen Blue) from aqueous solutions. Batch adsorption studies were carried out by monitoring the pH, the bio-adsorbent dose and the initial dye concentration. Attempts have also been made to monitor the adsorption process through Langmuir, Freundlich, Dubinin-Radushkevich, and Temkin adsorption isotherm models. These results have demonstrated the immense potential of mint waste as a bioadsorbent for dyes remediation in polluted water and wastewater. Finally followed by the process of adsorption phenomenon was achieved by fourier transform infrared spectrometer (FTIR), the results shows that the adsorption is mechanical trapping.
