Description

General description

Method: reflectometric with test strips and reagent 5 - 120 mg/l PO₄³⁻ Reflectoquant^®

The Reflectoquant Phosphate test includes test strips and all necessary additional reagents. It is suitable for determining orthophosphate in wastewater, soil samples, fertilizers and food. In sulfuric solution orthophosphate ions (PO43-) react with molybdate ions to form molybdophosphoric acid. This is reduced to phosphomolybdenum blue (PMB) that is determined reflectometrically on the RQflex. For pre-testing a sample in an economic and quick way to estimate the phosphate concentration and a possible dilution factor prior to using this quantitative method we recommend our semi-quantitative MQuant test strips for phosphate. Further quantitative determination methods can be found with our Spectroquant tests.

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).
