This study was performed using Alfisol as an adsorbent, both of which are important inorganic and organic pollutants, to adsorb Cadmium and Glyphosate. Before usage, the soil samples were air-dried and permitted to move through 2mm sieve while the normal protocols were used for its analysis. Kinetic data were tested with pseudo-first-order and pseudo-second-order models and it was concluded that all adsorbate adsorption models adopted pseudo-second-order kinetics, while an intraparticle diffusion model was used to research the nature and mechanism of adsorption procedures. For glyphosate, a complete linear intraparticle diffusion plot was obtained, indicating that intraparticle diffusion was the rate-control stage in its adsorption, but the opposite is the case for cadmium adsorption. Cadmium peak removal occurred after 50 minutes with an equilibrium of more than 250 minutes, while glyphosate peak removal occurred after 30 minutes. It can be inferred that Alfisol can be used successfully for both cadmium and glyphosate adsorption, thereby showing a possible method of environmental remediation.
