WebMay 4, 2015 · 1.065 g of stainless steel was dissolved in hydrochloric acid (chromium as Cr 3+ ) and diluted to 500.0 ml. A 50.00 ml sample was passed through a Walden reducer, where only iron is reduced (Fe3+ + e- Fe2+), and titrated with 0.01920 M KMnO4 solution, which consumed 13.72 ml. WebThe G-value of dichromate reduction caused by gamma radiation was determined. The value found, 0.397 is close to the values of the other authors. Two solutions with different concentrations of dichromate have been chosen to match two applicable dose ranges. The solution containing 0.5mM Ag2Cr20y in 0.1 M HCIO4 is applied to dose range dat three sixty
