Sažetak
Mass transfer between the liquid and the solid phase in the column reactor has been analysed from the derived form of the model breakthrough curves obtained for the binary (Pb+Zn) solution at different flow rates. Up to the inflection area on breakthrough curves, mass transfer through the liquid phase governed the rate due to a higher number of available active sites in zeolite. After the inflection area, the active sites were occupied and competition between Pb and Zn occurred. Thus the particle kinetics became more significant and controlled the overall rate of the (Pb+Zn) uptake onto zeolite particles.
