The concentration of MC-RR was detected by HPLC and results show that the rate constant is invariable with different MC-RR initial concentrations. Different ultrasonic frequencies can change the distribution and characteristic of vapour cavity, while pH value changes the structure and hydrophilic property of MC-RR and finally affects the reaction. When pH changes from 1.90 to 12.21, the rate constant decreases from 0.400 min-1 to 0.082 min-1. The degradation of MC-RR is inhibited by but, and Cl- can be omitted, while the sequence of influence from large to small is, , Cl-, . When sound-energy density increases, the rate constant increases. The degradation of MC-RR by ultrasonic followed a pseudo first-order kinetics.
