Abstract

Metode potensiometri merupakan metode mengukur beda-potensial keseimbangan antara elektroda indikator dan elektroda referensi tanpa mempertentangkan sel elektrokimia. Metode potentiometri bermanfaat sebagai alat uji klinik dan analisis biologi. Karakteristik potensial elektroda dilakukan dengan mendeteksi potensial dari molaritas dan pH larutan buffer menggunakan enzim urease melalui injeksi urea pada konsentrasi rendah, volume injeksi urea dan penentuan reaksi larutan apakah reversibel atau irreversibel. Bahan yang digunakan untuk larutan adalah buffer tris-HCl, buffer fosfat, KCl dan enzim urease sebabai analit urea. Hasil karakterisasi urea dalam larutan mempunyai respon terbaik pada volume injeksi dan molaritas urea (0.3 mL 0.001 M) untuk buffer tris-HCl pH 5.5 dan buffer fosfat pH 7.5, sedangkan (0.4 mL 0.001 M) dalam KCl 0.01 M. Kurva kalibrasi larutan buffer tris-HCl dan fosfat serta KCl tergolong reversibel perbedaan potensial (tegangan) lebih besar 100 mV.
