Abstract:
Hydrated iron oxide supported on resin (D301) was prepared as a new sorbent for the removal of glyphosate from wastewater. Batch adsorption studies were performed on glyphosate aqueous solutions with different initial glyphosate concentrations and temperatures. Experimental data were analyzed using the Langmuir and Freundlich isotherms, and the adsorption data were best fit to the Langmuir isotherm model. The thermodynamic parameters AG, AH, and AS also were calculated for the adsorption processes. Adsorption rate constants were determined using the pseudo-first-order and pseudo-second-order rate equations and Kannan-Sundaram intraparticle diffusion models. Adsorption of glyphosate clearly followed the pseudo-second-order model and was controlled by both film diffusion and intraparticle diffusion.
