β¦ Synopsis
adsorption of strontium (%r/90Y, EBmax = 2.214 MeV) on activated carbons has been studied following a radiochemical technique. The activated carbons were prepared from almond shells, and characterized by adsorption of N2 (77 K) and CO1 (298 K), mercury porosimetry and ash content.
The effect of equilibration time, pH, adsorbent and adsorbate concentrations and of various anions on the adsorption has been investigated.
