摘要：
A new extended Gran's method is proposed and applied for simultaneous determination of iron (II and III) species by potentiometric titration with potassium permanganate solution. Conditions for titrations providing unbiased results of analyses were chosen on the basis of equilibrium analysis (simulated titration). (C) 2001 Elsevier Science B.V. All rights reserved.
