1 Scope

This section provides cadmium, chromium, vanadium content determination with aluminum hydroxide filler and quasi boehmite in. This section applies to the filler aluminum hydroxide and boehmite Determination of cadmium, chromium, vanadium intended. Measurement range. 5 × 10-5% ~ Cd 5 × 10-3%; Cr 3 × 10-4% ~ 5 × 10-3%; V 3 × 10-4% ~ 5 × 10-3%.

2 principle of the method

The sample is dissolved in hydrochloric acid, in dilute hydrochloric acid medium, directly into the argon plasma excitation source, subjected to spectral measurement, with matrix matching method school Positive impact on the determination of the substrate.
