VISOCOLOR® ECO Phosphate • Colorimetric determination of phosphate • Ammonium molybdate reacts with phosphate 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: 0 · 0.2 · 0.3 · 0.5 · 0.7 · 1 · 2 · 3 · 5 mg/l PO4-P Sufficient for: 80 determinations Shelf life at least: 3 years Sea water suitability: yes Detectable with PF-12: yes • 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.
