| Abstract: | Leaching of granular solids can be described in terms of specific mass transfer functions of a simple mathematical form. The parameters can be determined by column leaching experiments under well known flow conditions. Initially available concentrations are obtained from batch experiments at high dilution. Total concentrations in the solids are determined independently to calculate the available fractions. The determination of the flow pattern is done by radiotracer measurements. Leachates are analyzed by various analytical methods including AAS and INAA. Total concentrations in the solids are determined by INAA preferably. |
