GB/T 223.23-2008 Iron,steel and alloy—Determination of nickel content—The dimethylglyoxime spectrophotometric method
Abstract
This part of GB/T 223 specifies the determination of nickel content by the direct photometry method using diketone oxime and by the spectrophotometry method using extraction and separation of diketone oxime. This part of the method I is applicable to the determination of nickel content in cast iron, iron powder, carbon steel, and alloy steel with a mass fraction of 0.030% to 2.00%; This part of the method II is applicable to the determination of nickel content in cast iron, carbon steel, alloy steel, and precision alloys with a mass fraction of 0.010% to 0.50%.
