Purpose: Phosphorus is an essential element for water quality control. Excessive amounts of phosphorus causes algal bloom in water, which leads to eutrophication and a decline in water quality. It is necessary to maintain the optimum amount of phosphorus present. During the last decades, various studies have been conducted to determine phosphorus content in water. In this study, we present a comprehensive overview of colorimetric, electrochemical, fluorescence, microfluidic, and remote sensing technologies for the measurement of phosphorus in water, along with their working principles and limitations. Results: The colorimetric techniques determine the concentration of phosphorus through the use of colorgenerating reagents. This is specific to a single chemical species and inexpensive to use. The electrochemical techniques operate by using a reaction of the analyte of interest to generate an electrical signal that is proportional to the sample analyte concentration. They show a good linear output, good repeatability, and a high detection capacity. The fluorescence technique is a kind of spectroscopic analysis method. The particles in the sample are excited by irradiation at a specific wavelength, emitting radiation of a different wavelength. It is possible to use this for quantitative and qualitative analysis of the target analyte. The microfluidic techniques incorporate several features to control chemical reactions in a micro device of low sample volume and reagent consumption. They are cheap and rapid methods for the detection of phosphorus in water. The remote sensing technique analyzes the sample for the target analyte using an optical technique, but without direct contact. It can cover a wider area than the other techniques mentioned in this review. Conclusion: It is concluded that the sensing technologies reviewed in this study are promising for rapid detection of phosphorus in water. The measurement range and sensitivity of the sensors have been greatly improved recently.

“…Phosphate concentrations in seawater tend to be very low, specially on surface waters of oligotrophic regions, where the concentrations are below the LOD of conventional analytical techniques [8]. New techniques have been developed to minimize the LOD [6,17], but these are expensive and are not always available to many labs with limited resources. For example, Ma et al [9] achieved a 0.5 nM LOD using a 2 m path length liquid waveguide capillary cell with a spectrophotometric detection; Kröckel et al [6] got a 14.5 nM LOD using a FIA technique with a fluorescent detection and Legiret et al [7] a 52 nM one with a microfluidic analyser using the vanadomolybdate method.…”

“…As a weak base, it contributes to the alkalinity of seawater [2] and is one of the parameters to take into account for ocean acidification studies [3][4][5]. Therefore, quantification of phosphate in aquatic environments is crucial, as shown by the many efforts on developing accurate, precise, reproducible and reliable methods [6][7][8][9][10]. Different analytical techniques have been used for the determination of phosphate in seawater, including colorimetry and spectroscopy, photoluminiscence, atomic spectrometry, electrochemistry and separative techniques such as ion chromatography, capillary electrophoresis, liquid waveguide capillary cell and high performance liquid chromatography [8,9,11].…”

“…The injected sample creates a zone and is carried by the fluid flow to a detector that measures absorbance, electrode potential or another physical factor continuously (Ruzicka and Hansen, 5 p. 15). UV-visible spectrophotometry, 8,9 potentiometry, 10 fluorescence, 11,12 pre-column derivatization ion-pair liquid chromatography, 13 ion-exclusion chromatographic separation and post-column derivatization, 14 chemiluminescence 15 and voltammetry 16 are among the most used detection and separation techniques available for phosphate analysis. UV-visible spectrophotometry is the most commonly used detection technique in FIA systems as it is rapid, practical and simple.…”
