The present invention relates to a purification method of hydrogen peroxide, which removes impurities in hydrogen peroxide using an anion exchange resin, a cation exchange resin, and a reverse osmosis membrane which is formed by coating a porous polymer support with a carbon nanomaterial. More particularly, the present invention relates to a purification method of hydrogen peroxide, which passes hydrogen peroxide through the reverse osmosis membrane and then through the cation exchange resin and the anion exchange resin. The purification method of the present invention reduces costs of purifying hydrogen peroxide by increasing duty cycle of the reverse osmosis membrane and increases production yield of purified hydrogen peroxide by passing hydrogen peroxide through the reverse osmosis membrane in advance. 본 발명은 다공성 고분자 지지체 위에 탄소나노물질이 코팅된 역삼투압막, 음이온 교환수지 및 양이온 교환수지를 사용하여 과산화수소의 불순물을 정제하는 방법에 관한 것으로, 보다 자세하게는 과산화수소를 다공성 고분자 지지체 위에 탄소나노물질이 코팅된 역삼투압막 통과 후, 양이온 교환수지 및 음이온 교환수지를 통과시키는 것을 특징으로 하는 과산화수소 정제방법에 관한 것이다.
