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
利用三價鐵與edta和h2o2形成穩定的深紫色三元絡合物，在氨性溶液中，當有氧化劑存在時，鎳與丁二酮肟形成酒紅色的絡合物，用吸收光度法可分別在519nm和538nm波長處測定鐵、鎳的含量， fe和ni的相對標準偏差分別為0 . 95和1 . 2 ；對實際樣品的測定結果與xps分析一致。 -
