锌与乙二胺的络合物于-1.44伏(Vs.S.C.E)处产生一个良好的灵敏吸附催化波,在0.0004～0.004及0.004～0.04μg ml~(-1)范围内,锌的浓度与波高成线性关系。研究了波的极谱特性。方法不需分离可直接测定金属镉、铜中的微量锌。
The complex of zinc and ethylenediamine produced a good sensitive adsorption catalytic wave at -1.44 V (Vs.SCE). The concentration of zinc in 0.0004 ~ 0.004 and 0.004 ~ 0.04 μg ml ~ (-1) Wave height into a linear relationship. The polarographic characteristics of the wave were studied. Method can be directly determined without separation of metal cadmium, trace zinc in copper.
