Operating parameters of atomic absorption spectroscopy for quantitative determination of chromium in chrome ores, chrome concentrates and tailings Chemistry

Abstract

The present paper endeavors to define operating parameters of the atomic absorption method of spectroscopy for quantitative determination of Chromium in crome ores, crome concentrates and tailings. A new method of preparing standard solutions (in combination with microwave acid digestion of standard samples) is proposed for designing calibration curves and explicating conditions of supplying acetylene gas mixture and nitrous oxide, which enhance the accuracy of results obtained from the quantitative determination of chromium.
