Adsorption removal of cesium from drinking waters: A mini review on use of biosorbents and other adsorbents

A highly hydrophilic water-insoluble nanofiber composite as an efficient and easily-handleable adsorbent for the rapid adsorption of cesium from radioactive wastewater

“…In most of the previous studies, the hybrid materials have showed the maximum adsorption rate of about 30-65 % after the soaking time of 10 min. [33][34][35][36][37][38][39] For instance, the magnetic hexacyanoferrate (II) 65 polymeric nanocomposite (RZ) showed the adsorption rate of ~65% after 10 min and the maximum adsorption rate of ~95% only after 150 h, 10 whereas the present c-PBNPs/PVA composite nanofibers showed a very higher Cs adsorption rate of ~96% after only a very less soaking time of 100 min (1.7 h). Similarly, the 70 present c-PBNPs/PVA composite nanofibers confirmed a better adsorption rate of ~96 % (100 min) when compared to the zirconium(IV) iodomolybdate exchanger (ZIM) (Fig.…”

Removal of Radioactive Cesium (134Cs plus 137Cs) from Low-Level Contaminated Water by Charcoal and Broiler Litter Biochar

“…Charcoal has been widely used as an adsorbent of radionuclides in various industries, including food processing, and is reported to adsorb iodine, radon, pertechnetate, thallium, and uranium (Klasson and Taylor, 2006;Rivera-Utrilla et al, 1984;Caccin et al, 2013); limited information about adsorption of radioactive cesium by charcoal exists. In general, these studies show that soluble cesium (radioactive or not) is not effectively removed by charcoal (Caccin et al, 2013;Kosaka et al, 2012;Rivera-Utrilla et al, 1984;Verzil et al, 1992;Liu et al, 2014).…”

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

“…24) These results indicated that the uselessness of M-IP6 for decorporation of 137 Cs in vivo was caused by the lower selectivity to Cs After centrifugation at 10000×g for 5 min at room temperature, the supernatant was removed and water was added to the precipitation. After the suspension was vortexed, it was centrifuged at 10000×g for 5 min at room temperature.…”
