GB/T 223.9-2008 Iron,steel and alloy—Determination of aluminium content—Chrome azurol S photometric method
Abstract
This part of GB/T 223 specifies the determination of the content of acid-soluble aluminum by the chromotropic S spectrophotometry method and the determination of aluminum by the chromotropic S spectrophotometry method after separating it with copper-iron reagent. This part of the method I is suitable for the determination of the content of acid-soluble aluminum in steel and alloys with a mass fraction of 0.050% to 1.00%; this part of the method II is suitable for the determination of the content of aluminum in steel and alloys with a mass fraction of 0.015% to 0.50%.
