Sažetak
The experimental breakthrough curves of zinc removal onto the 40 mm fixed bed depth of natural zeolite have been obtained. The results have been fitted to the Thomas empirical kinetic model and excellent agreement has been observed. The modelled curve has been derived in order to define the mass transfer mechanism using the reactor theory for packed beds. It can be seen that up to the inflection point on the breakthrough curve, the mass transfer through the aqueous phase governs the rate, while after the inflection point the diffusion through particles governs the overall rate.
