20.500.12556/DKUM-27460 Uncertainty of nitrate and sulphate measured by ion chromatography in wastewater samples This paper presents an evaluation of measurement uncertainty regarding the results of anion (nitrate and sulphate) concentrations in wastewater. Anions were determined by ion chromatography (EN ISO 10304-2, 1996). The major sources of uncertainty regarding the measurement results were identified as contributions to linear least-square or weighted regression lines, precision, trueness, storage conditions, and sampling. Determination of anions in wastewater is very important for the purification procedure, especially the amount of nitrate in waste and potable waters. The determined expanded uncertainty was 6% for nitrate anions and 8.3% for sulphate anions. The difference between measurement uncertainties determined by the two methods, the weighted and linear least-square methods is negligible. wastewater nitrates sulphates measurements measuring uncertainty odpadne vode nitrati sulfati meritve merilna negotovost true false true Angleški jezik Slovenski jezik Znanstveno delo 2012-06-01 11:17:31 2012-06-01 11:17:31 2022-04-15 13:44:57 2021-04-11 03:26:10 2007 0 0 str. 557-569 št. 2 Letn. 5 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1895-1066 628.3 11055638 11055894 10.2478/s11532-007-0002-3 1895-1066 URN:SI:UM:DK:SO9RIFYP Open_Chemistry_2007_Tepus,_Simonic_Uncertainty_of_nitrate_and_sulphate_measured_by_ion_chromatography_in_wastewater_samples.pdf Open_Chemistry_2007_Tepus,_Simonic_Uncertainty_of_nitrate_and_sulphate_measured_by_ion_chromatography_in_wastewater_samples.pdf 1 8943E33778137C870AD264DBA3ED0D93 195262d865033652fae055fd08893b9265eaca395e19827627692a9094362c8b 45da4d4d-7c07-11eb-bb7a-00155d0001ca 20.500.12556/dkum/4106d941-c6ee-4478-9fc6-8b20b3ba4e5b https://dk.um.si/Dokument.php?lang=slv&id=110527 http://www.degruyter.com/view/j/chem.2007.5.issue-2/s11532-007-0002-3/s11532-007-0002-3.xml 1 https://dk.um.si/Dokument.php?lang=slv&id=110528 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
