Sensing properties of chitosan and chitosan-roselle film sensors on toluene concentrations detection
Halimatussa'adiah, Adnan (Universiti Malaysia Perlis (UniMAP)School of Materials Engineering, 2013-10)This study aims to observe the sensing properties of chitosan sensor (CS) and chitosanroselle sensors (CRSs) on toluene at various concentrations. CRSs were deposited using various chitosan: roselle ratio of 99:1 to 89:11 ...
