This study aims to reveal the adsorption mechanism of materials prepared from hemp shives as co-products of the hemp industry, namely sodium carbonate-activated (SHI-C) and polycarboxylic agent-grafted (SHI-BTCA) hemp shives. The interactions between copper and two hemp-based materials were characterized by different microscopic and spectroscopic techniques such as energy-disperse X-ray (EDX) spectroscopy, computed nano-tomography (nano-CT), X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, and X-ray absorption near-edge structure (XANES) spectroscopy. The results showed remarkable different mechanisms for copper adsorption onto the SHI-C and SHI-BTCA hemp shives. Namely, copper surface adsorption and diffusion in the structure of the SHI-C material were predominant, whereas the adsorption of copper onto SHI-BTCA was due to a chemisorption phenomenon and ion-exchange involving the adsorbent carboxylate groups. The combination of the abovementioned complementary microscopic and spectroscopic techniques allowed us to characterize and distinguish the type of interactions involved in the liquid-solid adsorption phenomena.Show less >
