Abstract: For the removal of 2,4-D (2,4-dichloro-phenoxy-acetic acid) and atrazine (2-chloro-4-ethyalamino-6- isopropylamino-s-traiazine) from water environment, batch studies were performed to study the kinetics of 2,4-D and atrazine sorption by rubber granules. Experiments were conducted at various initial concentrations of 7.5 mg/ L, 4 mg/ L, and 0.5 mg/ L of 2,4-D and atrazine with 18 g/ L sorbent dose. The equilibrium time was found to be 120 minutes for both 2,4-D and atrazine. The regression analysis for the experimental data showed that the rapid stage zone of kinetics profiles followed a first order reversible kinetics for all initial concentrations of sorbate. The various thermodynamic properties such as enthalpy and entropy activation values (Delta H and Delta S) also show that the sorption is spontaneous. This article will provide information toward understanding the sorption phenomena of 2, 4-D and atrazine on waste tyre rubber granules. It also is valuable to us in finding out the rate constant of sorption of 2,4-D and atrazine.
