A new monitoring system to measure metals dissolved in water by means of room-temperature phosphorescence optical fiber sensors

In this paper a relatively simple, low-cost industrial prototype for measuring concentrations of metals dissolved in water is presented. The operation of this system is based on the measuring of the light emission intensity of the chemical sensors. This kind of system provides simultaneous on-line multiple measurements and it has major advantages over other present techniques, such as excellent sensitivity and stability, high precision and selectivity, good time response and low maintenance cost.
