Phosphate 45

Nanocolor ortho and total Phosphate 45

Photometric determination of phosphate

DIN method: ammonium molybdate reacts with orthophosphate ions to form phosphomolybdic acid. This is reduced to molybdenum blue. For the determination of total phosphate, an acidic oxidation at 100 – 120 °C must preceed to detect poly- and organic phosphates. (Reaction basis according to DIN EN ISO 6878-D11).

Occasional precipitations after the digestion can be filtered off with membrane filtration kit 0.45 µm (REF 916 50). In case of a high content of organic matter and/or organically bound phosphorus, we recommend digestion with NANOCOLOR® NanOx Metal (REF 918 978).

Determination of total phosphorus with NANOCOLOR® NanOx Metall

For phosphorus compounds which are difficult to oxidize, we recommend digestion with NANOCOLOR® NanOx Metal (REF 918 978).
