Terbium Removal from Aqueous Solutions Using a In₂O₃ Nanoadsorbent and Arthrospira platensis Biomass.

ABSTRACT: Terbium is a rare-earth element with critical importance for industry. Two adsorbents of different origin, In₂O₃ nanoparticles and the biological sorbent Arthrospira platensis, were applied for terbium removal from aqueous solutions. Several analytical techniques, including X-ray diffraction, Fourier-transform infrared spectroscopy, and scanning electron microscopy, were employed to characterize the adsorbents. The effect of time, pH, and terbium concentration on the adsorption efficiency was evaluated. For both adsorbents, adsorption efficiency was shown to be dependent on the time of interaction and the pH of the solution. Maximum removal of terbium by Arthrospira platensis was attained at pH 3.0 and by In₂O₃ at pH 4.0-7.0, both a
