Efficiency of biological versus mesoporous adsorbents for gadolinium removal from wastewater.

ABSTRACT: Gadolinium application in industry and medicine results in generation of large volumes of gadolinium-containing wastewater, which can present hazard for humans and environment. Adsorption proved to be an efficient way of metal removal from wastewater. Two adsorbents of different origin, yeast biomass and titanosilicate ETS-10, were applied for gadolinium removal from synthetic wastewater under different experimental conditions. Several analytical techniques, including scanning electron microscopy and X-ray diffraction were used for adsorbents characterization. The maximum removal of gadolinium by both adsorbents was achieved at pH 3.0. By studying kinetics, the applicability of the pseudo-first-order model for the description of gadolinium adsorption on analyzed adsorbents was shown. Langm
