High-Speed and High-Capacity Removal of Methyl Orange and Malachite Green in Water Using Newly Developed Mesoporous Carbon: Kinetic and Isotherm Studies

for the MO and MG, respectively). Methyl orange adsorption mostly occurred through ion exchange and electrostatic interactions, and at lower MO concentrations, through chemical interactions and surface complexation as well. Malachite green adsorption took place only on lower-energy sites. Thus, it can be concluded that the adsorbent proposed herein possessed high-speed and high-adsorption capacity. Therefore, it can be considered as promising in removing the reported dye pollutants.
