根据Fe3+离子与金属Al发生氧化还原反应 ,而不与Al2 O3 发生反应的原理 ,研究了金属Al与Al2 O3 分析的问题。该方法操作简便 ,流程短 ,结果可靠
Based on the principle that redox reaction between Fe3 + ion and metal Al occurs without reaction with Al2 O3, the problem of metal Al and Al2 O3 analysis is studied. The method is easy to operate, the procedure is short and the result is reliable
