Sažetak
Hydrodynamic conditions in the batch reactor are affected by reactor design, e.g. by the reactor size, impeller type and size, its position in the reactor and mixing speed. The influence of the mixing speed of two different turbine impellers, one with straight blades (SBT) and one with the inclination of the blades of 45° (PBT) on the sorption kinetics of copper ions on zeolite NaX has been studied. The experiment was conducted at constant suspension temperature in a batch reactor with baffles at four different impeller speeds and constant turbine impeller off-bottom clearance. The Ritchie model and Weber-Morris model were used to estimate the slowest process step and the models’ parameters. The kinetic analysis of the obtained kinetic experimental data showed that that the mixing speed, of both impellers, influence the process. According to the good matching of Ritchie's model and obtained data and AARD values can be stated that the reaction of copper ion sorption on zeolite NaX is kinetic controlled and follows the second-order kinetics.
