Abstract
Potentiometric characteristics are significantly dependent on the composition of the membrane and the properties of the plasticizer. Characterization of membrane electrodes was carried out using (UV-Vis to see absorbance, SEM-EDX to see the morphology and atomic ratio and XRD to see the intensity ratio of u.a). Characterization of PVA membranes: PVC in the composition of 1: 1 ie 0.0350 g PVA and 0.0350 g PVC, plasticizer 0.0100 g KTpClPB with variation of enzyme coating on PVA on 1x, 2x and 3x electrode membranes, followed by each coting 1x 0.0350 g PVC 0.0100 g KTpClPB. The electrode membrane selected was PVA E 1X PVC -KTpClPB 0.0100 g electrode membrane obtained optimum (absorbance, atomic ratio and intensity of u.a).
