摘要：

We present the details of a simple and reliable iodine-titration method suited for high-T(c) copper oxides, in which the use of a solution of ammonium acetate and acetic acid as a buffer agent substantially improves the operation. The results applied to La2-xMxCuO4-delta (M = Ba, Sr and Ca) are presented.
