Methods
Notes:
1. Filter turbid water samples using filter paper and funnel before analysis.
2. Highly buffered water samples or extreme pH values should be adjusted to a pH of
nearly 7 with 1 mol/l Nitric acid or 1 mol/l Sodium hydroxide.
3. Concentrations above 10 mg/l Cu causes too high test values if the reaction time of 5
minutes is increased. So it is very important to perform the test procedure as described.
4. Substances which may interfere when present in concentrations at:
Aluminum 50 mg/l
Chromium 1000 mg/l
Iron 50 mg/l
Nickel 50 mg/l
Nitrite all levels
