Sažetak
The aim of this work was to determine the influence of hydrodynamic conditions generated by Rushton turbine (RT), in the baffled and unbaffled batch reactor, on just suspended impeller speed (N JS ), power consumption (P/m), maximum amount of copper exchanged onto zeolite NaX (q e ) and exchange kinetics as well. The amount of exchanged copper at examined conditions was determined using UV/Vis spectrophotometer. Elovich and Blanchard models were used to fit the experimental kinetics data. From the results of the studies of influence of the hydrodynamic conditions generated by Rushton turbine in the reactor with or without baffles can be concluded that the maximum amount of copper exchanged is higher and reaction is faster in the baffled reactor, which is characterized by higher just suspended impeller speed value. But at the same time power consumption per unit mass of suspension is more than three times higher in a baffled reactor. Since the difference in the maximum amount of copper exchanged and the kinetics rate in baffled and unbaffled reactors isn’t significant unlike the power consumption, unbaffled reactor stirred by RT may be advisable for studied operation. Analysis of kinetic data show that the process studied follows second order kinetic.
