有关硝酸根和亚硝酸根的脉冲极谱测定已有报导,还未见有羟胺的导数脉冲极谱研究报导。基于变价离子和高价阳离子存在下呈现平行于电极反应的极谱催化波和电催化波测定硝酸根和亚硝酸根已早有论述,但是同时呈现催化和电催化波的现象及其机理未见论述。作者发现了这一现象并进行了机理探讨。另外,借Yb(Ⅲ)-NO_3(NO_2)体系测定NO_3~-及Yb(Ⅲ),以往都认为铵离子的存在是必不可少的主要成分。作者在没有铵离子
Pulsed polarographic measurements of nitrate and nitrite have been reported and no studies have been reported on the derivative of polarography of hydroxylamine. The determination of nitrate and nitrite by polarographic and electrocatalytic waveforms, which are parallel to the electrode reaction in the presence of the variable-valent ions and high-valent cations, has been discussed for a long time, but the phenomena of catalytic and electrocatalytic waves and their mechanisms are not discussed . The authors discovered this phenomenon and conducted a mechanistic discussion. In addition, the determination of NO_3 ~ - and Yb (Ⅲ) by the system of Yb (Ⅲ) -NO_3 (NO_2) has been considered as the essential component of the existence of ammonium ion. The authors did not have ammonium ions
