The aim of this study was to optimize a process of phytic acid extract for the rice bran and into test on the corrosion inhibition of copper H62. Phytic acid was extracted by using combined process technology of microwave and ultrasonic wave from rice bran, and this work present the results of the microwave and ultrasonic wave studies of Phytic acid extracted. Orthogonal experiment was used to study the optimum extraction process of phytic acid. The Phytic acid on copper H62 was evaluated by weight-loss measurements, metallographic microscopic analysis and electrochemical methods. The results demonstrated that ultrasonic treatment time was 20min, microwave treatment time was 3min, acid leaching time was 1.5h, the ratio of raw material and solution was 1: 9, the extraction rate of phytic acid was 6.75%; Generation plant power circulating water system was simulated, the inhibition rate of copper H62 was 94.16% when phytic acid concentration was 5mg/L.
