Insights on the Adsorption Properties of Functionalized Polyketone for Diclofenac Sodium Removal.

ABSTRACT: Aliphatic polyketones, known for their low cost, simple synthesis, and ease of functionalization, have gained attention as potential wastewater treatment materials. However, their application for pharmaceutical removal remains underexplored. To investigate their feasibility as drug adsorbents, the polyketone was modified with four functional groups: hydroxyl, amine, imidazole, and benzene rings, using a one-step Paal-Knorr reaction. This catalyst- and solvent-free reaction is simple, generating water as the sole byproduct. The modified polyketone adsorbents were evaluated for their ability to remove diclofenac sodium, a pharmaceutical compound frequently detected in water resources. Batch adsorption experiments revealed that polyketone modified with amine groups exhibited the highest adsor
