Hybrid materials (AAS (Al-AMBA-sericite and AHS (Al-HDTMA-sericite)) was obtained and materials are characterized by XRD, SEM and IR analytical techniques. Hybrid materials were assessed for efficient removal of diclofenac from aqueous solutions. Increasing the diclofenac concentration (1.0 to 20.0 mg/L) and pH 2 to 7 favored greatly the removal of diclofenac by AAS and AHS. Background electrolyte concentrations from 0.0001 to 0.1 mol/LNaCI, insignificantly affected percent removal of diclofenac. The breakthrough results were fitted well to the Thomas equation and hence, loading capacity of diclofenac was found to be 0.561 and 1.056 mg/g for MS and AHS, respectively.
