| Summary: | Remediation of copper (II) pollutant in aquatic ecosystems is a long-standing concern in the field of water management and the subject of intensive research. In this study, chitosan conjugated iodate porous material (CS-CI) was successfully prepared by media (ammonia, acetic acid, and absolute ethanol) and was used in the treatment of Cu (II) in wastewater samples. Different methods were applied to characterize the CS-CI, including FTIR, SEM, XRD, and TGA. The result showed significant improvement in surface properties and stability when the chitosan was conjugated with the iodate. The adsorption of Cu (II) followed the pseudo-first-order kinetic model and Langmuir isotherm model with a maximum adsorption capacity of 95.2 mg/g. In a complex system (real wastewater), the CS-CI took advantage of the adsorptive properties of both chitosan (CS) and the iodate to significantly improved the remediation of Cu (II) in aqueous media. Therefore, the synthesized chitosan conjugated iodate porous material is promising as an alternative low-cost adsorbent for the treatment of copper (II) in wastewater.
