General description

Method: colorimetric, PMB, with color-disk comparator 0.2 - 0.4 - 0.6 - 0.8 - 1.0 - 1.5 - 2.0 - 2.5 - 3.0 mg/l PO4-P MQuant®
The MQuant® Phosphate test (formally MColortest®) can be used for the determination of orthophosphate in:
  • Groundwater and surface water, seawater
  • Drinking water and mineral water
  • Waters from aquaculture
  • Industrial and process water
  • Wastewater
  • Soils and fertilizers after appropriate sample pretreatment
  • Food after appropriate sample pretreatment
  • Steels after appropriate sample pretreatment

Method
In sulfuric solution orthophosphate ions react with molybdate ions to form molybdophosphoric acid. Ascorbic acid reduces this to phosphomolybdenum blue (PMB). The phosphate concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid and colored water samples can be analyzed without further preparation. The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas and wet environments.
Using the refill pack 1.18465 containing all the reagents, the original test kit can be used for a very long time, making it a particularly economical and ecological system.
