Removeable Interferences
1. Interference from niobium, tantalum, titanium, and zirconium are masked with citric
acid.
2. Interference from vanadium(V) is masked with potassium fluoride.
3. Under test conditions (pH 3.8 – 3.9) iron does not react. Other metals at levels
likely to be found in industrial water systems do not interfere at any significant level
either.

Preparation
1. Strong alkaline or acidic water samples must be adjusted between pH 3 and pH 5
before the analysis (use 0.5 mol/l Sulphuric acid or 1 mol/l Sodium hydroxide).
2. To avoid errors caused by deposits, rinse the glassware with Hydrochloric acid
(approx. 20%) before the analysis and then rinse with deionised water.
