20.500.12556/DKUM-67411 A silver/silver sulphide selective electrode prepared by means of chemical treatments of silver wire Priprava elektrode srebro/srebrov sulfid s kemično obdelavo srebrne žice The preparation and usability of a sulphide ion selective electrode, prepared by means of chemical pretreatment of silver wire with an ammonium perdisulphate solution, and the sulphidization in an alkaline sulphide solution are described. The electrode is suitable for direct potentiometric measuring of sulphide in alkaline solutions of concentrations down to ▫$1 X 10^{-6} mol/L$▫. The 45 min required for each chemical treatment are enough for the preparation of the described electrode. Opisujemo pripravo sulfidne ionoselektivne elektrode s kemijsko obdelavo srebrne žice v amonijevem peroksodisulfatu in alkalni sulfidni raztopini. Elektroda omogoča direktne potenciometrične meritve koncentracij sulfidnih ionov v alkalnih raztopinah navzdol do ▫$10^{-6} mol/L$▫. Priprava elektrode je enostavna in hitra. analytical chemistry ion selective electrode preparation silver wire potentiometric measurements sulphide ions analizna kemija ion selektivna elektroda priprava srebrna žica potenciometrične meritve sulfidni ioni true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-08-17 08:55:46 2017-08-17 08:59:14 2022-08-01 13:56:32 2019-07-11 16:19:29 1998 0 0 str. 209-216 št. 3 Letn. 45 1998 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 543.554.6:546.57 14086149 19517445 1318-0207 URN:SI:UM:DK:NWIKEPLO Acta_Chimica_Slovenica_1998_Dobcnik_et_al.A_silver_silver_sulphide_selective_electrode_prepared_by_means_of_chemical_treatme.pdf Acta_Chimica_Slovenica_1998_Dobcnik_et_al.A_silver_silver_sulphide_selective_electrode_prepared_by_means_of_chemical_treatme.pdf 1 9C4D0AC9CAC2AFDA791E0FCC6C43C40C 2b95b5e980222ce3b46676779f6e2301cbe3a5ad117e4a4c91cb664416088630 84e7622f-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/8f84f6fd-b19c-44d5-b603-d782bb53f727 https://dk.um.si/Dokument.php?lang=slv&id=115407 http://acta-arhiv.chem-soc.si/45/45-3-219.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=115406 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
