Beschreibung
Zusammenfassung:	The present invention relates to a method for surface treatment inside a high-purity hydrogen fluoride storage container, which comprises: a cylinder pretreatment step of removing moisture inside a cylinder; and a fluoride passivation film forming step of using anhydrous hydrofluoric acid to form a fluoride passivation film on an inner surface of the cylinder. It is possible to provide a method for surface treatment and a high-purity hydrogen fluoride storage container surface-treated according to the same method, capable of minimizing the generation of impurity gases such as hydrogen and oxygen even during long-term storage of high-purity hydrogen fluoride. 본 발명은 실린더 내부의 수분을 제거하는 실린더 전처리단계; 및 무수불산을 이용하여 실린더 내부 표면에 불화부동태막을 형성하는 불화부동태막 형성단계;를 포함하는 고순도 불화수소 저장 용기 내부의 표면처리방법에 관한 것으로, 고순도 불화수소의 장기간 저장 시에도 수소, 산소 등의 불순물 가스의 발생량을 최소화시킬 수 있는 표면처리방법 및 이에 따라 표면처리된 고순도 불화수소의 저장 용기를 제공할 수 있다.
