Abstract

The paper presents an investigation of sensitivity and response time of a chitosan coated-plastic optical fibre (POF) sensor to cadmium ion concentration. The sensor working principles is based on the change of light intensity transmitted by the chitosan coated POF due to the change of cadmium ion concentration. Three sensor probes were fabricated with various coating thickness which are 100.24m (sensor A), 131.97 m(sensor B) and 376.24m (sensor C). The characterization was done by exposing the sensor to cadmium ion solution for various concentrations. The results showed that sample C provides the lowest sensitivity while sample B showed the highest sensitivity which are 15.04mA/ppm and 65.64mA/ppm, respectively. In terms of response time, it was showed that sample A has the highest average response time which is 20.5seconds.
