抄録

The methods for the determination of the available oxygen in manganese and reduced manganese ores with sodium oxalate and with ferrous sulfate were examined. The result of analysis of pure synthesized manganese dioxide indicated that the sodium oxalate method gave positive errors, because sodium oxalate was decomposed by manganous manganese and air, but gave a good result when correction was made for the amount of the decomposed salt. The result of ferrous sulfate method was in good agreement with theoretical values. Although both the methods gave negative errors when the samples used contained ferrous compounds, reasonable results could be gained if corrections were made for the ferrous iron in the sample which had been preliminary determined by means of phosphoric acid solution containing sodium sulfite, as reported in Part 5.
