INVESTIGATION ON DETERMINATION OF Al2O3 AND F- IN ARTIFICIAL GYPSUM BY SPECTROPHOTOMETRY METHODS USING ALUMINUM - ALUMINON COMPLEX

Abstract

Spectrophotometry methods using Aluminon reagent and ascorbic acid
scrub for determination of Al2O3 and F- content was investigated. The suitable
conditions for Photometry measurement were studied and established. The
studied method was employed for the determination of Al2O3 and F- in some
artificial gypsum samples with good precision and accuracy.
