摘要
The sorption of radiocobalt from aqueous as well as organic solvents by natural and treated clays has been investigated. The effect of many factors, such as time, pH, carrier concentration, etc., were studied. In was found that the uptake is maximum in neutral, or slightly alkaline solutions. The rate of sorption depends on the velocity of shaking, which may indicate the operation of the film-diffusion mechanism, in addition to some contribution from particle-diffusion mechanism, but the dependence of the rate on shaking velocity could be attributed to an increase in the surface area of the clays. The conclusion is that natural clays are well suited for the removal of radioactive cobalt with slight, if any modification. These clays may be considered superior to synthetic exchangers for the removal of60Co, if the availibility and prices of the former are taken into account. © 1990 Akadémiai Kiadó.
