Scope

This part of GB/T 20975 specifies the determination method for the content of cerium, lanthanum and scandium in aluminum and aluminum alloys. This part is applicable to the determination of cerium, lanthanum and scandium in aluminum and aluminum alloys. Aluminum in aluminum and aluminum alloys interferes with the determination of cerium, lanthanum and scandium. Add an equal amount of aluminum to the working curve to eliminate interference. The three elements of lanthanum and scandium do not interfere with each other, and other coexisting elements do not interfere with the determination. Measuring range: cerium: 0.005%~0.90%, lanthanum: 0.005%~0.50%, scandium: 0.000 2%~0.50%.
