Studies on the Rates of Exchange of Hg (II), Cd(II), La(III) and Ce(III) ions in Sodium Nitrite-Aqueous acetone Media Using an Anion-Exchanger Dowex-1 X 8(NO-3)

Abstract

Rate of exchange has been studied on Hg(II), Cd(II), La(III) andCe(III) ions in sodium nitrite-aqueous acetone media using an anionexchanger Dowex-1 x 8(NO3^- ). Acetone was used to provide solventmedia of 10%, 30% and 50% and temperature was used in ratestudies, carried out at 30°, 40°, 50°C. Always 1 g. of Dowex-1 x 8 in nitrate form was used for distribution studies to get ratedata. After suitable time intervals aliquots (1 mL) were withdrawnand metal ion concentration was found out.
