VISOCOLOR® alpha Phosphate • Colorimetric determination of phosphate • Ammonium molybdate reacts with phospat ions to form phosphomolybdic acid which is reduced to molybdenum blue. (Reaction basis according to DIN EN ISO 6878-D11) Type: colorimetric test kit Range: 2 · 5 · 10 · 15 · 20 mg/l PO43- Sufficient for: 70 determinations Shelf life at least: 2 years Sea water suitability: yes Detectable with PF-12: no • The phosphate content in a surface water has direct consequences for its ability to support the growth of certain organisms. • Since ever increasing quantities of phosphates are being fed through domestic waste waters into rivers and lakes, these waters have a tendency towards eutrophication. • Exact data about the phosphate content are important for boiler water and feed water. • Precise dosing of phosphates in these waters can inhibit formation of boiler scale. • Pyro-, meta- and polyphosphates are not determined with VISOCOLOR® test kits. • The determination of total phosphate requires a decomposition prior to the test.
