Photometric determination of aluminium
Photometric determination with eriochrome cyanine R. In weakly acidic solution aluminum ions react with eriochrome cyanine R to form a red-violet colored complex.
Strongly acidic and buffered samples have to be adjusted to pH 6. Turbid solutions have to be filtered (membrane filters 0.45 µm, REF 916 50).
