Abstract AITranslate

In view of the off-standard contents of the copper,iron and some other impurities in high-purity niobium oxide produced in a company,the causes of the quality accident are analyzed. The results indicate that the nitric acid mixed in hydrofluoric acid can rapidly oxidize 2-octanol into organic acid in extraction process. The resultant organic acid interferes with the acid pickling process of the niobium oxide,resulting in the off-standard impurity （i. e. copper and iron） contents in the product.
