Abstract
The study and the development on an optical fibre sensor for the detection of pH is described. Phenol red, immobilized on XAD-2 microspheres, was used as pH indicator. Particular care was devoted in the planning and construction of the probe in order to obtain high sensitivity and good signal levels. The measuring apparatus is described as well as experimental results are reported.File in questo prodotto:
