摘要: Glass comprising B2O3-Al2O3-Na2O-ZnO with doping iron metal powder has been melted at 1200 degrees C undermicrowave heating. The identical batch was in resistive UV-Vis-NIR spectroscopy employed to determine the ferrous ion intensity glass within 1000-1200 nm wavelength and recorded spectra for both glasses indicate higher retention of oxidation state borate microwave Iron redox ratio (Fe2+/total Fe) is investigated by spectiophotometric method developing ferrozine colour complex Fe2+ glass. Ferrozine chosen as a specific reagent, which forms deep violet Fe2+, broad absorbance peak centered similar 562 nm. spectrophotometric using reveals 0.34 0.29 obtained from conventional heating respectively. Another 1, 10 ortho-phenanthroline also demonstrates Thus, favours more stabilization zinc glass, unlike (C) 2016 Elsevier Ltd. All rights reserved
