eurjchem-882	Zannat, Tasnima; Ahmed, Mohammed Jamaluddin	A simple and rapid spectrophotometric method for the determination of iron in environmental, biological, pharmaceutical, food and soil samples using 1,2-dihydroxybenzene-3,5-disulfonic acid	2014	10	.pdf	application/pdf	6923	391	61	ARTICLE INFORMATION ABSTRACT DOI: 10.5155/eurjchem.5.1.101‐110.882 Received: 18 July 2013 Received in revised form: 07 September 2013 Accepted: 07 September 2013 Online: 31 March 2014 KEYWORDS An ultra‐sensitive and highly selective non‐extractive spectrophotometric method is presented for the rapid determination of iron (III) at trace levels using 1,2‐dihydroxybenzene‐ 3,5‐disulfonic acid (Tiron) as a new spectrophotometric reagent (max = 665 nm) in slightly acidic aqueous (2×10‐6 ‐ 2×10‐5 mol/L H2SO4) solution. The method was successfully used in the determination of iron in several standard reference materials (Alloys and steels) as well as in some environmental waters (portable and polluted), biological samples (Human blood and urine), food, pharmaceutical and soil samples, solution containing iron (II) and iron (III) and some complex synthetic mixtures.	cache/eurjchem-882.pdf	txt/eurjchem-882.txt
