Zusammenfassung:The present invention relates to an electrolyte used in a process of treating a film by anodizing an aluminum alloy, wherein with respect to 100 parts by weight of the electrolyte, comprises 2-5 parts by weight of a main ingredient of an oxalic acid and 1-4 parts by weight of citric acid as an auxiliary material respectively and an electrolyte solution according to the anodized film treatment is prepared, and various environmental pollutants generated in a process of disposing the electrolyte solution can be reduced by maintaining the electrolyte solution at a temperature range of 10-30°C to form an oxide film having a thickness of 15-42 μm on a surface of the aluminum alloy, and adding oxalic acid and citric acid, which are natural products, to the electrolyte solution of the aluminum alloy in a state that excludes strong acids that cause micropores. 본 발명은 알루미늄합금의 양극산화에 의한 피막처리의 과정에서 사용하는 전해액에 관한 것으로, 상기 전해액 100 중량부에 대하여, 주재료인 옥살산 2~5 중량부 및 부재료인 구연산 1~4중량부를 각각 포함하여 상기 양극산화 피막처리에 따른 전해액을 조성하고, 상기 전해액을 10~30oC의 온도범위로 유지하여 상기 알루미늄합금의 표면에 15~42㎛ 두께의 산화피막을 형성함으로써, 상기 알루미늄합금의 전해액에 미세기공의 생성원인이 되는 강산을 배제한 상태에서 천연물인 옥살산 및 구연산을 첨가함으로써, 상기 전해액의 폐기과정에서 발생하는 각종 환경오염원을 줄일 수 있다.
