Abstract
U ovom radu dobiven je slabo topljiv talog LaF 3 sutaloženjem NaF i La(NO 3 ) 3 s europijem. Bijeli puderasti talog sušen je u sušioniku na 60˚C. Pripravljane su membrane različitih debljina, zbog veće čvrstoće u membrane dodavan je teflon. Odzivne karakteristike elektrode ispitivane su metodom slijednog razrijeđenja počevši od koncentracije fluorida 10 -1 do 10 -7 molL -1 . Kako bi se dobile bolje odzivne karakteristike na površinu membrana nanošene su nanočestice Fe x O y . Pripravljene membrane nisu pokazale očekivane odzivne karakteristike, promjena potencijala po dekadi znatno je niža od teorijske vrijednosti (59 mV) i iznosila je 15 mV. Dodatak nanočestica nije znatno poboljšalo odzivne karakteristike. Dodatak europija u različitim postotcima (0,3 %, 1%, 3%) nije znatno poboljšao odzivne karakteristike.
Abstract (english)
In the present thesis, sparingly soluble LaF 3 was obtained by precipitating NaF with La(NO 3 ) 3 with the addition of europium.The white powder-like precipitate was put in the dryer at 60˚C. The membranes of different thicknesses were prepared, after which the Teflon was added in order to make membranes harder. Response characteristics were tested by using the serial dilution method with concentrations of fluoride ranging from 10 -1 to 10 -7 molL -1 . Fe x O y nanoparticles were deposited on the membrane surfaces in order to receive better response. The prepared membranes did not show any kind of response that was expected, which is due to potential change towards decades being around 15 mV, which is much lower than the theoretical value (59 mV). The addition of europium ofdifferent percentages (0,3%, 1% and 3%) did not significantly improve response characteristics of membranes.
