Oxygen in nickel compounds was determined by the Unterzaucher method. Nickel perchlorate, organic-acid salts of nickel, such as nickel formate, nickel acetate and nickel oxalate, and nickel complexes and organic nickel compound, such as bis(2,3-butanedione dioximato) nickel, bis(2,4-pentane dionato) nickel, hexaammine nickel diperchlorate and tentraaquo (2,2'-bipyridine) nickel sulfate were used as samples. Oxygen in these samples was determined precisely by the usual method. Oxyten in nickel chloride with crystal water was also determined precisely by the same method. On the other hand, the amount of oxygen in nickel oxide, nickel nitrate and nickel sulfate was(5〜17)% less than the calculated balue. For the compounds whose total oxygen could not be determined precisely with the usual method, the authors designed the carrier gas method using reaction agent. In this paper naphthalene was used as reaction agent. The results of oxygen determination in nickel oxide, nickel nitrate and nickel sulfate were in good agreement with those of their calculated balues with this method. About 40 min was required for one determination.
