摘　　要：建立测定不锈钢中镍的丁二酮肟快速光度法。镍的浓度在0.5～1.1mg/50 mL与吸光度呈线性关系,测定结果的相对标准偏差为0.48％～0.96％。该方法简便、快速,节约试剂,测定结果准确。The method for the determination of nickel in stainless steel by rapid spectrophotometric with diacetyldioxime is set up. The linear range is 0.5-1.1 mg/50 mL. The relative standard deviation is 0.48%-0.96%. The method is simple and rapid, saves reagent and the result is accurate.
