GB/T 4698.1-2017 《Methods for chemical analysis of titanium sponge, titanium and titanium alloys—Part 1：Determination of copper content—Flame atomic absorption spectrometry》 Related products

This standard specifies a method for the determination of copper content in titanium sponge, titanium and titanium alloys by flame atomic absorption spectroscopy (AAS), suitable for samples with a copper content in the range of 0.10% to 5.00%. The method involves dissolving the sample with muriatic acid and hydrofluoric acid, masking the fluoride ions with saturated Boricacid, and measuring the copper Absorbance in an air-acetylene flame. The standard provides a detailed description of the reagents, instruments and operation procedures, providing specifications for the accurate determination of copper in titanium and titanium alloys.
