✦ 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.

Activated carbons of very different nature and pore size distribution have been characterized by gas adsorption and by adsorption from solution; the results have been compared with a simpler method proposed by Puri (retention of ethylene glycol) and a new test proposed here (retention of n-nonane).

Phenol adsorbs in two ways on activated carbons: by physisorption and chemisorption. During the course of time and by raising the tempera~re, chemiso~t~on is increased and part of the physisor~ phenoi becomes chemisorbed. This phenol is impossible to remove as such. Upon heating to elevated temperat
