摘　　要：铂钯合金用盐酸、硝酸溶解，采用电感耦合等离子体发射光谱法测定合金中的铑和铱。针对该合金中铂、钯所占比例不同，准确建立了铑、铱的元素分析谱线、背景干扰、仪器参数等实验条件。测定的铑、铱相对标准偏差均小于1．5％，加标后的回收率在99．83％～100．15％，分析结果令人满意。Simultaneous determination of Rh and Ir in environmental samples was carried out by inductively coupled plasma atomic emission spectrometry （ ICP -AES） after platinum palladium alloys dissolved with hydriochloric acid and nitric acid . Optimal experimental conditions including analytical spectral line , back‐ground interference and instrument parameter were investigated and established according to the different proportion of Rh and Ir in alloys .The present methodology gave recoveries between 99 .83% and 100 .15%and RSD less than 1 .5% , w hich make the result satisfactory .
