Optical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...

متن کاملFiber-optic Temperature Sensor Semiconductor Etalon
This paper describes a fiber-optic temperature sensor that uses a spectrum-modulating Sic etalon. The spectral output of this type of sensor may be analyzed to obtain a tem.+ perature measurement which is largely independent of the transmission properties of the m sensor's fiber-optic link. A highly precise laboratory-type spectrometer is described in detail, and this instrument is used to stud...
متن کاملPhotonic porous silicon as a pH sensor
Chronic wounds do not heal within 3 months, and during the lengthy healing process, the wound is invariably exposed to bacteria, which can colonize the wound bed and form biofilms. This alters the wound metabolism and brings about a change of pH. In this work, porous silicon photonic films were coated with the pH-responsive polymer poly(2-diethylaminoethyl acrylate). We demonstrated that the pH...
متن کاملSoil calcium and pH monitoring sensor system.
An agrarian sensorial system based on temperature, moisture, and all solid-state ion-selective potentiometric sensors was developed with the objective of monitoring the behavior of H+ and Ca2+ ions in soil and in real conditions, contributing with a new tool that tries to complement the current precision agriculture technology. The evaluation of the sensorial system to pH monitoring presented a...
