Abstract

In this study, chitosan/exfoliated graphite (CEG) sensors were used for formaldehyde detection in various concentration i.e. 1 ppm; 1,5 ppm; 2 ppm; 5 ppm; and 10 ppm. The sensors were fabricated using electrodeposition method to form film sensors. The cross-linking agent is glutaraldehyde, it was used to enhance the life time of CEG film sensors. The effect of exfoliated graphite concentration on sensing properties of CEG film sensors has been proven by improvement on response and sensitivity of sensors when the concentration of EG increased. Formaldehyde solution was dropped onto chitosan/EG film sensor and the response of the chitosan/EG film sensors toward formaldehyde was recorded as output voltage. The measurement result of maximum output voltage from chitosan/EG film sensors is greater than chitosan sensors for 10 ppm formaldehyde. Increasing on concentration of formaldehyde made the output voltage of the sensors increased.
