Title: Spectrophotometric studies on the investigation of chromium in environmental samples. Author: Melwanki MB, Seetharamappa J. Journal: Indian J Environ Health; 2003 Jan; 45(1):25-8. PubMed ID: 14723280. Abstract: Isothipendyl hydrochloride is proposed as a sensitive and selective reagent for the rapid spectrophotometric determination of chromium(VI). The reagent instantaneously gives a red coloured species on reaction with chromium(VI) in phosphoric acid medium which exhibits maximum absorbance at 510 nm with Sandell's sensitivity of 2.28 ng cm(-2). Beer's law is valid over the concentraction range of 0.1-1.9 mg/l with an optimum concentration range of 0.2-1.7 mg/l. The method has been successfully applied to the analysis of chromium in environmental samples.[Abstract] [Full Text] [Related] [New Search]
