本文在不同pH的Britton-Robinson缓冲溶液中和羟胺存在时,在-0.6至-0.7伏(对饱和甘汞电极)(其电位随溶液组成而改变)得到钌(Ⅲ)还原为二价的催化波。对此催化波的极谱性能如波高-汞柱高度关系,波高-滴落时间关系,波高-温度关系,波高-浓度关系,波高-溶液组分关系等进行实验。

In the presence of hydroxylamine, the catalytic wave of ruthenium (Ⅲ) appears at -0.6 to 0.7 V (S.C.E.) (depending on the composition of the solution) in Britton-Robinson buffer solution. The polarographic behaviour of this catalytic wave is studied by means of the dependence of the wave behaviour on the composition of the polaro-graphic solution and on the height of the mercury reservoir, the time beater, the temperature dependence, etc.
