摘　　要：提出一种用氯酸钠作氧化剂精密电流滴定测定铱的方法,考察了氧化条件、氯酸钠用量及酸度对测定的影响。对Pt—Ir及Rh—Ir合金试样分析结果表明,此法相对误差为0.1％。A method for the determination of iridium by precision amperometric titration with NaClO_3 as oxidizer is presented. The effects of conditions of oxidation, amount of NaClO_3 and acidity on the determination of iridi um is studied. The analysis of iridium in Pt-Ir and Rh-Ir alloys indicated that the relative error is 0.1%.
