The study includes a demonstration of the removal of janus green dye from aqueous solutions by an available and inexpensive surface, which is flint clay. The effect of several conditions on the adsorption process was applied, including contact time, adsorption dose, size of adsorbent surface particles, initial concentration of dye, and temperature. Analyze the study data dynamically and found that it follows the pseudo-second order model. It also analyzed the equilibrium data and found it to follow the Langmuir isotherm model. The thermodynamic functions of the dye adsorption process were calculated and found to be a not easy-to-occur and irregular process of an endothermic nature of the type of physical adsorption.
