GB/T 7731.14-2008 Ferrotungsten—Determination of lead content—The polarographic method and inductively coupled plasma-atomic emission spectrometry
Abstract
This section specifies the determination of lead content in tungsten iron by polarography and inductively coupled plasma atomic emission spectrometry. This section is applicable to the determination of lead content in tungsten iron. The determination range (mass fraction): 0.001% to 0.12%. Among them, polarography is suitable for the determination of lead content with a mass fraction of 0.001% to 0.05%; inductively coupled plasma atomic emission spectrometry is suitable for the determination of lead content with a mass fraction of 0.010% to 0.12%.
