Abstract:This study aims to synthesize and characterize PVA-Enzyme/GA/PPy/PVC-KTpClPB-o-NPOE indicator indicator electrodes, XRD and FTIR analysis and variable signal analysis for urea sensors. The method used is biosensor potentiometry with urease enzyme immobilization technique which analytes urea. Modify 6 mg of enzyme from the amount of 1 drop and 3 drops in 0.5 mL (50% water: 50% ethanol) in PVA solution and o-NPOE plasticizer in PVC-KTpClPB. The indicator electrode is designed in multi-membrane, namely PVA-Enzyme… Show more
