Abstract

This review covers the advantages of phosphorus determination in environmental objects such as saline and fresh water, soil, human serum and urine, food and fertilizers for the period of 2000-2018 years. Both spectrophotometry and spectrophotometry combined with liquid or solid-phase extraction, flow-analysis system, electrochemical, luminescent and visual test-system are considered. Spectrophotometry stays the most multipurpose method (is capable for analysis of different objects), cost-effective, despite of the rapid progress of electrochemical sensors. Flow-analysis systems are successfully implemented for surface and groundwaters analysis, also for saline water. Complex multicomponent luminescent and voltamperometric systems are used for phosphorus determination in biological matrices, e.g. serum and blood plasma, urine. Test-systems can provide simple and express reactive phosphate monitoring without using of complex devices. Yet the limitation of columns with color band formation is the short range of determined phosphate concentrations; some components of paper-based test-systems are affected by UV radiation.

Keywords: phosphate determination, heteropoly acid, water analysis, biological samples
