Sažetak
Taguchi's approach to experimental design was applied to determine the effect of some process parameters on the sorption of copper ions onto zeolite NaX. The impact of solute concentration (c), temperature (T), contact time (t), impeller speed (n) and anion type (A) on the amount of copper retained on the zeolite, in a batch stirred reactor, was investigated. Optimum experimental conditions and influence of controllable factors were determined using larger-the-better approach. The applied method showed that the optimal copper removal is achieved at the lowest solute concentration, when sulphate anions were used, at the highest impeller speed and temperature used and after 45 min. The influence of controllable factors in descending order is c > n > A > T > t. Also, the impact of anion type, solute concentration and temperature on the process equilibrium was examined. The experimental data were modelled using Langmuir, Freundlich and Sips isotherms and their goodness-of-fit was analysed. Thermodynamic parameters such as G0, H0, and S0 were also determined. According to the thermodynamic parameters copper sorption on zeolite NaX was a spontaneous and endothermic process for all anions used.
