HCK Colortest Polyphosphates

Measurement of the color intensity of the blue complex formed by reduction of Phosphomolybdic acid obtained from the reaction of Orthophosphate with Ammonium Molybdate.

1 – 2,5 – 5 – 10 – 15 – 20 ppm P3O105-
The scale is based on Sodium polyphosphate Na5P3O10

- Note: This kit requires the use of a thermoreactor (100°C for 30 minutes) or a small pot with boiling water (100°C for 30 minutes)
- The optical comparator in the package allows for color comparison between two test tubes containing the same amount of water, benefiting accuracy.
- INTERFERENCES.
The presence of other forms of phosphorus such as metaphosphates and orthophosphates from false positives.
Iron > 0.5 ppm.
Arsenic > 1 ppm.
Fluorides > 10 ppm.
Chromates > 100 ppm.
Chlorides > 1000 ppm.
Other substances normally present in water do not interfere.
