An investigation of the absorption spectra of EGTA metal complexes and the development of spectrophotometric methods for the analyses of copper, erbium, europium, holmium, neodymium, and praseodymium

Creator:: Holmes, Ivan Gregory
Abstract:: The reactions of EGTA, [ethylene bis (oxyethylenenitrilo)] tetraacetic acid, with 51 metal ions have been studied spectrophotometrically in aqueous solutions. The absorption spectra of the chelates formed were measured with a recording spectrophotometer between 200 and 700 mμ. The pH of each solution was varied and a spectrum was scanned...

Spectrophotometry of molybdenum, tungsten and chromium chelates of quercetin

Creator:: Mitchell, Lloyd James
Abstract:: Quercetin (3, 3', 4', 5, 7-pentahydroxyflavone) reacts with hexavalent molybdenum, tungsten and chromium to form chelates soluble in an ethanol-water medium. This color reaction has been investigated with a view to its possible application in the spectrophotometric determination of trace amounts of these metals. In the development of the method,...

An investigation of the crystal growth of the heavy metal sulfides in supercritical hydrogen sulfide

Creator:: Lewis, Leroy Crawford
Abstract:: Solubility studies on the heavy metal sulfides in liquid hydrogen sulfide at room temperature were carried out using the isopiestic method. The results were compared with earlier work and with a theoretical result based on Raoult's Law. A relative order for the solubilities of sulfur and the sulfides of tin,...
