GB/T 3654.6-2008 Ferroniobium—Determination of sulfur content—Combustion-iodate titrimetric method,methylene blue photometric method and infrared absorption method
Abstract
This section specifies the determination of the sulfur content in niobium iron by the iodometry, methylene blue photometry, and infrared absorption methods. This section is applicable to the determination of the sulfur content in niobium iron. The determination range (mass fraction) of the iodometry method is 0.035% to 0.090%; the determination range (mass fraction) of the methylene blue photometry method is 0.0050% to 0.035%; and the determination range (mass fraction) of the infrared absorption method is 0.0050% to 0.090%.
