Abstract
Ispitan je odziv ionsko-selektivnih membrana na niklove(II) ione pri pH = 4 i pH = 5, te utjecaj dodatka različitih postotaka nanočestica željezovih i aluminijevih oksida na odziv membrana. Membrane su sastavljene od niklovog(II) sulfida, srebrovog sulfida i teflona koji osigurava čvrstoću membrane, dok su nanočestice magnetita, hematita, akaganeita te aluminijeva oksida dodavane u postotcima od 1, 0,5 i 0,25 %. Ukupno je testirano 13 membrana uključujući referentnu membranu te su grafički prikazani rezultati koji su pokazali najbolji odziv. Svako mjerenje je ponovljeno minimalno tri puta. Ispitivanje odziva izvršeno je potenciometrijski zbog jednostavnosti i praktičnosti metode. Membrane su se ispitivale u elektrokemijskoj ćeliji koristeći otopinu niklovog(II) sulfata, pripremljenu u otopini perklorne kiseline pH=1 i u 0,1M otopini klorovodične kiseline pH=2, metodom slijednog razrjeđivanja. Za svako mjerenje zabilježena je vrijednost elektrodnog potencijala.
Abstract (english)
The response of ion-selective membranes to nickel(II) ions at pH = 4 and pH = 5 was tested, as well as the influence of the addition of different percentages of nanoparticles of iron and aluminum oxides on the response of the membranes. The membranes are composed of nickel(II) sulfide, silver sulfide, and teflon, which ensures the strength of the membrane, while nanoparticles of magnetite, hematite, akaganeite, and aluminum oxide were added in percentages of 1, 0.5, and 0.25%. A total of 13 membranes were tested, including the reference membrane, and the results that showed the best response are shown graphically. The response test was performed potentiometrically. The membranes were tested in an electrochemical cell using a nickel(II) sulfate solution, prepared in perchloric acid solution pH=1 and in 0.1M hydrochloric acid solution pH=2, using a similar dilution method.
