ALUMINIUM Eriochrome cyanine-R Method
Range: 0.02 – 1 mg/L Al
PRINCIPLE:
The automated procedure for the determination of Aluminium is based on the Eriochrome cyanine-R Method. Aluminium forms a complex with eriochrome cyanine using a buffer at PH 6.4
Ascorbic acid is used to eliminate interference.
This complex is measured at 540 nm
