摘要：
A new kinetic study of the uncatalyzed bromate oscillator using dark tea without pre-treatment was carried out. The difference of dark tea oscillating system with and without manganese ion as catalyst was compared. The reaction was studied with different starting concentrations of the reagents (sulfuric acid and potassium bromate) and the substrate of dark tea, and the results indicate that the concentration of dark tea has a wide range between 1 with 30 g/L in dark tea-KBrO3-H2SO4 system, the lowest concentration of potassium bromate and sulfuric acid are 0.028 mol/L and 0.24 mol/L. The effec...
