GB/T 4324.8-2008 Methods for chemical analysis of tungsten—Determination of nickel content—The inductively coupled plasma atomic emission spectrometry、flame atomic absorption spectrometry and dimethylglyoxime gravimetry
Abstract
This method specifies the determination method for the nickel content in tungsten powder, tungsten rods, tungsten carbide, tungsten trioxide, tungstic acid, blue tungsten, purple tungsten, ammonium para-tungstate, and ammonium metatungstate. This method is suitable for the determination of nickel content in tungsten powder, tungsten rods, tungsten carbide, tungsten trioxide, tungstic acid, blue tungsten, purple tungsten, ammonium para-tungstate, and ammonium metatungstate. The determination range is 0.0004% to 0.050%.
