DZ/T 0424.1-2022 《Methods for chemical analysis of graphite ores s- -Part 1 : Determination of silicon, aluminum，calcium , magnesium, ferrum, titanium, manganese and phosphorus contents-Sodium carbonate alkali fusion一inductively coupled plasma atomic emission spectrometry》 Related products

This document stipulates the use of sodium carbonate melt-Inductance coupled plasma atomic emission spectroscopy (AES) method (ICP-AES) to determine the content of silicon, aluminum, calcium, mg, iron, titanium, manganese and phosphorus in graphite ore. Applicable to the determination of these elements, the method detection limit and determination range are detailed in Table 1. Users should have formal laboratory work experience and take appropriate safety and health measures. The document refers to GB/T 6682, GB/T 14505 and other documents to ensure that the test meets the requirements of relevant national regulations.
