Abstract
The adsorption of radioantimony (122Sb and124Sb) on pyrolysis residue, bentonite and fly ash from its solutions in benzene, toluene and xylene was investigated. The radioactivity of the isotopes was measured in the organic solution above the adsorbents as a function of time. After 24 h, the sequence of uptake of Sb(V) in benzene and toluene is: pyrolysis residue>bentonite>fly ash, while in xylene it is bentonite>pyrolysis residue>fly ash. The maximum lg kD value was 3.37 for the toluene-pyrolysis residue system. Desorption of Sb(V) from the loaded material was studied using both tap water and 1M HCl. The latter has more desorption power, evidently, due to hydrolysis and production of insoluble species in the neutral medium.
