Verfahrens-Dokument
Aluminum reacts with pyrocatechol violet (PCV) at pH 6.2 to form a colored complex that absorbs at 580 nm. Hydroxylamine hydrochloride and orthophenanthroline are added to reduce and mask iron interferences. This method applies to samples preserved with nitric acid (0.15% v/v). If total aluminum is to be measured, a digestion with hot nitric acid is required.
