In addition , we use spectrophotometric to study the compositions of nickel - iron alloy prepared by electrodeposition , and the main results are as follows : iron ( ) forms a stable deep purple complex with ethylenediaminetetraacetic acid disodium salt ( edta ) and hydrogen peroxide in aqueous solution at ph = 10 . 7 - 11 . 3 ; nickel ( ) forms a red complex with dlacetyl dioxime in aqueous ammonia when an oxidation ( iodine ) exists ; thus the amount of iron ( ) and nickel ( ) can be determinated by the absorption of their complexes at 519nm and 538nm respectively 利用三价铁与edta和h2o2形成稳定的深紫色三元络合物，在氨性溶液中，当有氧化剂存在时，镍与丁二酮肟形成酒红色的络合物，用吸收光度法可分别在519nm和538nm波长处测定铁、镍的含量， fe和ni的相对标准偏差分别为0 . 95和1 . 2 ；对实际样品的测定结果与xps分析一致。
