Abstract
Glavni cilj ovoga završnog rada je testiranje odziva membrana za ion-selektivne elektrode na Fe 3+ katione u otopini željezova(Ⅲ) nitrata pri pH=1 i pH=1,5 kao i utvrđivanje mogućnosti njihove praktične primjene. Testiranje odziva membrana izrađenih od mješavine željezova fosfata, srebrova sulfida i politetrafluoroetilena u omjeru 1 : 1 : 2 uz dodatak nanočestica cinkovog oksida i aluminijevog okshidroksida izvršeno je potenciometrijskom metodom upravo zbog ekonomičnosti postupka te jednostavnosti izvedbe. Odziv na željezove(Ⅲ) katione ispitan je kod 6 različitih membrana pri pH=1 te pH=1,5: • Membrana PNA4, PNA5 i PNA6 sastava FePO 4 : Ag 2 S : PTFE = 1 : 1 : 2 sa 0,25%, 0,5% i 1% nanočestica aluminijeva okshidroksida • Membrana PNZ1, PNZ2, PNZ3 sastava FePO 4 : Ag 2 S : PTFE = 1 : 1 : 2 sa 0,5%, 1% i 1,5% nanočestica cinkova oksida Ispitan je odziv na Fe 3+ katione u otopini željezova(Ⅲ) nitrata metodom slijednog razrijeđenja uz pufer nitratnu kiselinu-HNO3 (pH=1 i pH=1,5). Mjerenja su uglavnom ponavljana 3 puta uz bilježenje promjene potencijala te vremena odziva. Rezultati testiranja odziva na poslijetku su prikazani grafički.
Abstract (english)
The main goal of this bachelor tesis is to test the response of membranes for ion-selective-electrodes to Fe3+ cations in a solution of iron(Ⅲ) nitrate at pH=1 and pH=1,5, as well as to determine the possibility of their practical use. Testing the response of membranes made of a mixture of iron phosphate, silver sulfide and Teflon in a ratio of 1: 1: 2. was performed by the potentiometric method precisely because of the economic procedure and simplicity of performance. The response to iron(III) cations is tested for 6 different membranes at pH=1 and pH=1,5: • Membranes PNA4, PNA5 and PNA6 composition FePO 4 : Ag 2 S : PTFE = 1 : 1 : 2 with 0,25%, 0,5% and 1% nanoparticles of aluminium oxyhydroxide • Membrane PNZ1,PNZ2 and PNZ3 composition FePO 4 : Ag 2 S : PTFE = 1 : 1 : 2 with 0,5% , 1% and 1,5 % nanoparticles of zinc oxide The response to Fe 3+ cations was tested in a solution of iron(Ⅲ) nitrate by sequential dilution with nitric acid pufer-HNO 3 (pH=1 and pH=1,5). Measurements are generally repeated 3 times, writing down the changes in potential and response time. The test results of the responses in the end were shown graphically.
