Summary This standard specifies the determination method of aluminum oxide content in bismuth concentrate by chrome azuroine S photometry and Na2EDTA titration. This standard is applicable to the determination of aluminum oxide content in bismuth concentrate. The determination range (mass fraction) of chrome azuroine S photometry is 0.10% to 5.00%, and the determination range (mass fraction) of Na2EDTA titration is 5.00% to 10.00%.
