GB/T 3286.9-2014 Method for chemical analysis of limestone and dolomite.Part 9: The determination of carbon dioxide content.The caustic asbestos absorption gravimetric method (English Version)
This part of GB/T 3286 specifies the determination of carbon dioxide content by the caustic soda asbestos absorption gravimetric method. This section applies to the determination of carbon dioxide content in limestone and dolomite, and also applies to the determination of carbon dioxide content in metallurgical lime. The determination range (mass fraction) in limestone and dolomite: the carbon dioxide content is 30%~50%; the determination range (mass fraction) in metallurgical lime: the carbon dioxide content is greater than 0.50%.
