Abstract: The effect of amoxicillin on the Belousov-Zhabotinsky oscillating chemical reaction was studied. Addition of amoxicillin was found to perturb both the oscillation period and amplitude. The changes of the oscillation period and the amplitude are linearly proportional to the concentration of amoxicillin in the range of 1.5×10-5~2.4×10-3 mol/L and 4.7×10-5~4.8×10-3 mol/L with the regression coefficients of 0.9822 and 0.9846, respectively. The oscillation mechanism of the present system was discussed briefly with FKN mechanism.
