- Abstract
Natural palygorskite has a restricted adsorption capacity. The uranium ion removal ability of thermally modified palygorskite (T/Pal) beads from simulated wastewater was evaluated. T/Pal and T/Pal beads were characterized by several analytical methods. The influence of pH, contact time, temperature, and initial U(VI) concentration on the adsorption of T/Pal beads was investigated. The adsorption efficiency of U(VI) by T/Pal beads reached 99% within 20 min and the adsorption capacity was 20.23 mg g−1 at 313 K. The reusability of T/Pal bead was demonstrated by five sorption-desorption cycles. T/Pal beads are promising, economical adsorbents for the recovery of U(VI), and for radioactive wastewater decontamination.
