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
Abstract
This part of GB/T 3286 specifies the determination of carbon dioxide content by the method of absorbing weight with caustic soda and asbestos.
This part is applicable to the determination of carbon dioxide content in limestone and dolomite, and also to the determination of carbon dioxide content in metallurgical lime. The determination range (mass fraction) in limestone and dolomite: carbon dioxide content 30% to 50%; the determination range (mass fraction) in metallurgical lime: carbon dioxide content greater than 0.50%.
