説明

Organic acid salts of indium, such as bis(benzoate-O)hydroxy indium, bis(2-methyl benzoate-O)hydroxy indium and bis(trichloro acetate-O)hydroxy indium, and indium complexes, such as tris (2-methyl-8-quinolinolate)indium, tris(2, 4-pentane-dionate-O, O')indium and tris (8-quinolinolato) indium, were used as samples. Oxygen in these samples was determined precisely by the usual method. Oxygen in indium, chloride with crystal water was also determined precisely by the same method. On the other hand, the amount of oxygen in indium oxide, indium hydroxide and indium nitrate was determined as less than the calculated value by a factor of (814) %. For the compounds whose total oxygen could not be determined precisely with the usual method, the authors designed the reaction-gas-addition-carrier-gas-method. In this paper hydrogen was used as a reaction gas. The results of oxygen determination in indium oxide, indium hydroxide and indium nitrate were in good agreement with those of their calculated values with this method. One analysis required approximately 40 min.
