摘要: The dissolution behavior of CeO2 in sulfuric acid was examined using a batch reactor with various concentrations (8–14 M) at different temperatures (75–130°C). slow and it took more than 3 days to dissolve 4 mmol powder completely 100 mL 12 M 90°C. rate increased increases the temperature concentration. could be expressed by shrinking sphere kinetics model. variation constant obeyed Arrhenius equation activation energy 120 kJ mol−1. reaction function concentration as C6.5.
