A paper-based microfluidic device for reactive phosphate measurement is proposed. The detection is based on the molybdenum blue reaction. The working range is 0.2–10mgL1 P and the detection limit is 0.05mgL1 P. The device was successfully applied to natural water and soil water samples.doi:...
The uncertainty of phosphate measurement in offshore water in the East China Sea was studied with the general method.By analyzing the effective factors of measurement uncertainty,such as the specific measurement environment,the standard materials used,the sampling volume,mole quality,etc., the standard...
The intensity of the blue colored complex formed (molybdenum blue) is directly proportional to the concentration of phosphate (PO43-). This application describes how UV Vis spectroscopy can be used to determine the trace level of phosphate in water at the working concentration of around 2.0 ppm....
Most phosphorus exists within one of the many forms of phosphate molecules. Phosphorus in the Environment Phosphorus is vital within our freshwater ecosystems because it is the limiting nutrient for algae. Eutrophication, or excess nutrients within a body of water, can be harmful due to the potenti...
This white paper describes how control of silica and phosphate at power plants require different strategies. With reliable, actionable insights from on-line monitoring, plant personnel gain confidence to take the necessary actions to extend asset lifetim
PURPOSE:To measure the concentration of phosphorus accurately preventing the generation of interference noise by inclining a phosphosilicic acid glass film to an incident infrared ray to measure the absorption spectrum. CONSTITUTION:A phosphosilicic acid glass (PSG) film 1 formed on an Si substrate is...
Measured nitrate and dissolved orthophosphate levels in the river reached as high as 10 M and 3.6 M, respectively. Fast Fourier transform analysis suggests a strong out-of-phase relationship between measured phosphate and water level, ... E Luy,J Smith,I Grundke,... - Frontiers in Sensors ...
The minimum detection limit of labile phosphate of this method was 0.300mgP/L, and the maximum detection limit could reach 50.00mgP/L. The DET-CID technique can be used to measure labile phosphate in a wide range of acidic and alkaline water bodies (pH=2-10 and water hardness from 0 ...
