GB/T 14506.6-2010 Methods for chemical analysis of silicate rocks—Part 6:Determination of calcium oxide content
Abstract
This part of GB/T 14506 specifies the method for determining the amount of calcium oxide in silicate rocks.
This part is applicable to the determination of the amount of calcium oxide in silicate rocks, and also to the determination of the amount of calcium oxide in soils and aquatic sediments.
Determination range: Ethylene glycol bis (ethyl ether diamine) tetraacetic acid (EGTA) complexometric titration method, 1%~15% calcium oxide content. Flame atomic absorption spectrometry, 0.1%~5% calcium oxide content.
Note: The EGTA complexometric titration method is not applicable to silicate rock samples with a total content of strontium and barium greater than 0.4%.
