Phosphate Reagent Powder Pillows 0,02 - 2,50 mg/L PO4

Description

Packaged reagents Powder Pillows (212528) for the determination of Orthophosphate from Hach.

Аpplication: For drinking water, wastewater and seawater.

The reagents are hermetically sealed in foil sachets, which provides them with a long shelf life. The reagent is simply poured into the measuring cuvette along with the sample. The analysis is carried out visually, for example using a color disc or with a HACH LANGE photometer.

Summary of method: Orthophosphate reacts with molybdate in an acid medium to produce a mixed phosphate/molybdate complex. Ascorbic acid then reduces the complex, which gives an intense molybdenum blue color.
