Oxygen measurement via phosphorescence: reaction of sodium dithionite with dissolved oxygen.
A homemade instrument for the measurement of oxygen concentration in aqueous solutions measures the decay rate of the phosphorescence of a Pd-porphyrin complex (phosphor) dissolved in the solution, which is flashed every 0.1 s with 630 nm light. The concentration of O2 is a linear function of the decay rate. The instrument is used to study the reaction of dithionite (S2O42-) with O2 at 25 degre...
متن کاملA Tool for Measuring Oxygen via Phosphorescence
Accurate measurements of dissolved O2 as a function of time have numerous biological and chemical applications. Detection of O2 using a Pd phosphor complex is based on the principle that the phosphorescence of this probe is inversely related to dissolved [O2]. Biologic samples are flashed with red light using special instrumentation that captures emitted light and a customized software program ...
متن کاملA Dissolved Oxygen Measurement Based on Fiber Optical Oxygen Sensor
For the determination of dissolved oxygen, working principle of the fiber optic oxygen sensor is studied. The sensor system calibration method and temperature compensation measures and their maintenance methods are analyzed. The dissolved oxygen sensors current widely using oxygen electrode and optical fiber oxygen sensor are compared. Optical fiber probe sensor is used in the current system, t...
متن کاملTracer monitored titrations: measurement of dissolved oxygen.
The tracer monitored titration (TMT) technique is evaluated for measurement of dissolved oxygen. The TMT developed in this work uses a simple apparatus consisting of a low-precision pump for titrant delivery and an optical detector based on a white LED and two photodiodes with interference filters. It is shown that the classic Winkler method can be made free of routine volumetric and gravimetri...
متن کاملmeasurement and simulation of dissolved oxygen in zayande rood river
background: zayandeh-rood river is the only perennial river in the central basin of iran that has fresh water. water from this source is used for drinking, industrial and agricultural purposes. drinking water is extracted from upstream portion (upstream of chamaseman dam) of zayandeh-rood river and therefore its quality is very important. due to growth of population, industry and other factors,...
