Summary:
This standard is applicable to the determination of calcium oxide in biotite granite, rhyolite, granodiorite, quartz hornblende andesite, olivine basalt, gabbro, trachyandesite, neon syenite, sandstone, shale and other silicate rocks with similar composition. The EGTA complexometric titration method is not applicable to rock samples with a total strontium and barium content greater than 0.4%. Determination range: EGTA complexometric titration method, 1% to 15% calcium oxide. Flame atomic absorption spectrophotometry, 0.1% to 5% calcium oxide. This standard complies with the provisions of GB/T 14505.
