摘　　要：对11种金属离子与羟胺、乙二胺混合配体形成络合物的可见光谱特征、摩尔吸光系数、络合比、络合稳定常数以及加入甲醛后的特征吸收峰的吸光度变化进行了测定。为建立新的金属离子-羟胺-乙二胺络合体系分光光度测定痕量甲醛含量方法提供可靠的理论与实验依据。Visible spectral character, apparent molar absorptivifies, molar ration and stability constants of the complexes system of 11 metal ions - Hydroxylamine - Ethylenediamine were studied. And the absorption peak of absorbanee change by adding formal- dehyde has been measured. The 11 metal ions include Co^2＋ . Co^3＋ , Cr^3＋ .Cu^2＋、Fe^3＋ . Fe^2＋ .Hg2^2＋ .Hg^2＋ . Ni^2＋ .Pd2^＋ . V（ V ）. It may provide reliable theoretical basis and abundant experimental basis for a new speetrophotometrie method about the determination of trace formaldehyde.
