Abstract

In this study, chitosan was crosslinked with glutaraldehyde to fabricate a formaldehyde sensor. Chitosan based sensor was used for formaldehyde detection in various concentration (1 ppm; 1,5 ppm; and 2 ppm). The sensor fabrication was performed using electrodeposition method to form a film sensor. The crosslinking agent is glutaraldehyde, the aim of adding glutaraldehyde is to enhance the sensing properties of chitosan sensor especially the life time of the sensor. The existence of glutaraldehyde which was crosslinked with chitosan has been proved by FTIR spectra. Formaldehyde was dropped onto chitosan film surface and the response of the chitosan sensor towards formaldehyde was recorded as output voltage. The average of output voltage values for three times measurements were within the range of 0,0143 V to 0,0286 V. Increasing concentration of formaldehyde showed the increasing of output voltage value. The sensors showed good sensitivity and fast response.
