Prussian blue caged in alginate/calcium beads as adsorbents for removal of cesium ions from contaminated water

Facile synthesis of potassium copper ferrocyanide composite particles for selective cesium removal from wastewater in the batch and continuous processes

“…This occurred because that at low pH, ion exchange sites were mainly protonated, making them less available for cation. 25 However, when the pH increased, the sites became available for cation in ion-exchange processes, leading to higher adsorption. Even though, the adsorption capacity of cesium ions was feasible across a wide range of pH values, if the pH was at least 5 or above.…”

Complexes of <i>myo</i>-Inositol-Hexakisphosphate (IP6) with Zinc or Lanthanum for the Decorporation of Radiocesium

“…The maximum sorption capacity of Zn-IP6, La-IP6, and PB was estimated to be 203.0, 113.9, and 17.8 mg Cs/g, respectively. In previous reports, the maximum sorption capacity of PB has been reported to be 16.5 mg Cs/g at pH 8.6, 6) 158.5 mg Cs/g, 18) 12.5 mg Cs/g at pH 7.7 in seawater, 19) and 131.6 mg Cs/g, 20) depending on the study. While these values from previous study are different, the results of this study indicate that Zn-IP6 and La-IP6 possess much higher adsorption potency compared to PB, which has been approved as a decorporation agent for radiocesium.…”

Effective Adsorption of Pb(II) Ions by Gel Beads of Sodium Alginate and Polyethylene Glycol

“…The beads were separated through centrifugation, and the supernatant was analyzed by atomic absorption spectrometry. Removal rate was calculated as follows [15].…”
