Notes:
1. Only ortho-Phosphate ions react.
2. The tablets must be added in the correct sequence.
3. The test sample should have a pH-Value between 6 and 7.
4. Interferences:
Higher concentrations of Cu, Ni, Cr (III), V (V) and W (VI) interfere due to their colour.
Silicates doe not interfere (masked by Citric acid in the tablets).
5. See also page 213.
