Sažetak
The aim of this work was to determine the effects of anion type (A), time (t), impeller off-bottom clearance (C/H) and solute concentration (c) on copper exchange on zeolite NaX in a batch stirred reactor. The experiments were carried out at constant temperature (300 K) and at the same impeller speed (250 rpm). The amount of exchanged copper at examined conditions was measured by UV/Vis spectrofotometer. In order to find the optimal process conditions for copper exchange on the basis of experimental data, Taguchi’s method for experimental design were used, applying larger-the-better approach. Applied method has shown that the optimal copper exchange is achieved at increased solute concentration, when sulphate anion was used and impeller is positioned at standard position (C/H =0.33).
