Synthesis and characterization of a novel fish scale-immobilized chitosan adsorbent-Preliminary features of dichlorophenol sorption by solution calorimetry

► A novel fish scale-immobilized chitosan adsorbent was synthesized and characterized. ► It was evaluated the sorption of dichlorophenol on the new adsorbent. ► Simultaneous sorption data of quantity and energy were found by solution calorimetry. ► The interactions of fish scales/dichlorophenol are due to surface reactions. ► Excellent sorption features at adsorbent/dichlorophenol interface were found.
