肼的定量测定方法很多。标准酸直接滴定是最简便的方法,另一种是氧化法。为探索铀光化还原反应中肼量变化的分析,我们曾试用了:溴氧化法,碘氧化法,标准酸和碘酸盐联合滴定法,高锰酸钾法和分光光度法等。以上方法对铀光化还原UO_2(NO_3)_2制取U~(4+)的复杂体系,有的不能用,有的给出数据误差很大,鉴于以上原因,我对用N-溴代丁二酞亚胺 Hydrazine quantitative determination of many ways. The standard acid titration is the easiest method, the other is the oxidation method. In order to explore the change of the amount of hydrazine in the photochemical reduction reaction of uranium, we have tried: bromine oxidation method, iodine oxidation method, combined standard acid and iodate titration method, potassium permanganate method and spectrophotometry. The above method for the uranium photochemical reduction of UO_2 (NO_3) _2 Preparation U ~ (4 +) of the complex system, and some can not be used, and some give data error is very large, in view of the above reasons, I use N-bromobutyl Diaphthalimide
