GB/T 3286.5-2014 Method for chemical analysis of limestone and dolomite.Part 5:The determination of manganese oxide content.The periodate oxidation spectrophotometric method (English Version)
This part of GB/T 3286 specifies the determination of manganese oxide content by periodate oxidation spectrophotometry. This section applies to the determination of manganese oxide content (calculated as MnO) in limestone and dolomite, and also applies to the determination of manganese oxide content in metallurgical lime. Measuring range (mass fraction): manganese oxide content 0.005%~0.50%.
