General description

Method: colorimetric, PMB, with color card and comparator block with long test tubes 0.015 - 0.030 - 0.045 - 0.06 - 0.08 - 0.11 - 0.14 mg/l PO4-P 0.046 - 0.09 - 0.14 - 0.18 - 0.25 - 0.34 - 0.43 mg/l PO43- 0.034 - 0.07 - 0.10 - 0.14 - 0.18 - 0.25 - 0.32 mg/l P2O5 MQuant®
The MQuant® Phosphate test (formally MColortest®) can be used for the determination of orthophosphate in:
  • Groundwater and surface water, seawater
  • Drinking 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 card. The unique brilliance of the print and their fine color graduation allow precise analyses, even at the lower end of the concentration range.
Due to the long test tubes a sensitive measurement range can be covered.
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.

Application


  • Environmental Monitoring: Phosphate tests are extensively used in environmental monitoring to assess the levels of phosphate in water bodies. These tests help in evaluating the impact of agricultural runoff, industrial discharge, and wastewater treatment on water quality. Recent studies have focused on using selective colorimetric nano-sensing solutions to determine phosphate ions in drinking water samples, highlighting their importance in ensuring safe and clean water supplies (Salem and Draz, International Journal of Environmental Analytical Chemistry, 2020).
