2. Bajuk-Bogdanović, Danica V., 1977-. Ispitivanje stabilnosti 12-volframfosforne, 12-volframsilicijumove i 12-molibdenfosforne kiseline u rastvorima.

Degree: Fakultet za fizičku hemiju, 2016, Univerzitet u Beogradu

Fizička hemija - Fizička hemija materijala / Physical Chemistry - Physical Chemistry of Materials

12-volframfosforna (WPA), 12-volframsilicijumova (WSiA) i 12-molibdenfosforna kiselina (MoPA) su heteropoli kiseline (HPK) koje pripadaju velikoj klasi jedinjenja koja se nazivaju polioksometalati. U osnovi struktura ovih kiselina je Keggin-ov anjon (KA) čija se hidrolitička stabilnost razlikuje od kiseline do kiseline, što je utvrđeno ULj, IC, ramanskom i 31P NMR spektroskopijom. Najmanje je stabilna MoPA, kod koje roditeljska Keggin-ova struktura u razblaženim rastvorima (2∙10-5 moldm-3) nije prisutna čak ni pri pH < 1,0, a u koncentrovanim rastvorima (5∙10-2 moldm-3) egzistira samo pri pH < 1,0. WPA je stabilnija, i kod nje je roditeljski anjon prisutan pri pH < 1,0 u razblaženim, odnosno pH < 1,5 u koncentrovanim rastvorima. Najstabilnija je WSiA, kod koje je KA prisutan u razblaženim vodenim rastvorima do pH = 8,5 odnosno do pH = 6,4 u koncentrovanim rastvorima. Korišćenje 50 % metanola kao rastvarača dovodi do stabilizacije KA u ovim kiselinama, tako da se u slučaju MoPA javlja sve do pH = 3,5 i u razblaženim i u koncentrovanim rastvorima. Za WPA u koncentrovanim rastvorima oblast pH u kojoj se javlja KA se proširuje do pH = 2,5, a u razblaženim čak i do pH = 7,0. Najstabilnija WSiA se dodatno stabiliše u prisustvu metanola, pa se KA javlja sve do pH = 11,5 u razblaženim, odnosno pH = 7,8 u koncentrovanim rastvorima. Proces dekompozicije WPA je delimično reverzibilan, a za vodene rastvore je potvrđena vremenska stabilnost u toku jedne godine. Prilikom upotrebe pufera za podešavanje pH vrednosti rastvora HPK, mora se voditi računa o mogućoj interakciji HPK sa puferom, kao što je to slučaj pri primeni TRIS pufera. Dobijeni rezultati se mogu iskoristiti za utvrđivanje oblika HPK prisutnih u različitim sistemima. U slučaju polianilin - WPA mikro/nanostruktura KA je dominantno prisutna vrsta, ali se identifikuju i male količine Dawson-ovog i monolakunarnog KA. WPA i WSiA u inkubacionom medijumu (uz prisustvo enzima Na+/K+_ATPaze i ATP), u obliku monolakunarnog KA, inhibiraju dejstvo enzima Na+/K+_ATPaze, što je od značaja za različite biohemijske procese.
