Abstract
Elektrode na bazi paste od ugljika (CPE) su posebne heterogene ugljikove elektrode koje čini smjesa ugljikovih pasti pripravljenih s različitim udjelima grafita, veziva, ionsko-asocijacijskog kompleksa, soli. CPE imaju široku primjenu u određivanju elektrokemijski aktivnih spojeva. U ovom radu pripravljen je potenciometrijski senzor na bazi paste od grafita uz PMA i TPB kao anionskog dijela IAC-a za određivanje acebutolola u realnim uzorcima. Pripravljene su i testirane 22 paste s različitim udjelima grafita, tekućih veziva (TEPh, DEHA, NPOE) i IAC-a (ACBTPB, ACBPMA) pri pH vrijednosti 5. U paste s najboljim odzivnim karakteristikama dodana je mala količina soli NaTPB-a. Najbolje odzivne karakteristike pokazala je pasta 16 pripravljena od 54,8% grafita, 44,8% TEPh-a, 0,3% IAC-a ACB PMA i 0,1% NaTPB. Promjena potencijala po koncentracijskoj dekadi je u rasponu od -36,3 mV do -51,8 mV. Elektroda je drugi dan mjerenja nakon prvog poliranja pokazala najbolju promjenu potencijala po koncentracijskoj dekadi od -51,0 mV odnosno -51,8 mV u području linearnosti od 3,16×10 -6 M do 3,16×10 -3 M. Vrijeme uspostave stabilnog odziva je 60 s.
Abstract (english)
Carbon paste electrodes are special group of heterogeneous carbon electrodes mixture of carbon pastes are prepared with different parts of grahite, binder, ion-association complex and salt. CPE are widely used as working electrodes for the determination of electrochemically active compounds. In this experiment are prepared the potentiometric sensor based on graphite paste with tetraphenylborate and phosphomolybdate as anionic part of ionic-association complex for determination of acebutolol in real samples. 22 pastes with different proportions of graphite, liquid binders (TEPh, DEHA, NPOE) and IAC (ACBTPB, ACBPMA) were prepared and tested at pH 5. A small amount of NaTPB salt was added to the pastes with the best response characteristics. The best response characteristics were shown by paste 16 prepared from 54.8% graphite, 44.8% TEPh, 0.3% IAC ACB PMA and 0.1% NaTPB. The change in potential per concentration decade ranges from -36.3 mV to -51.8 mV. On the 2 nd day of measurement after the 1 st polish, the electrode showed the best potential change per concentration decade from -51.0 mV and -51.8 mV in the linearity range from 3.16×10 -6 M to 3.16×10 -3 M. The time to establish a stable response is 60 s.
