摘要
将双（乙腈）二氯化钯用硝酸、高氯酸消解,以混合酸溶解样品,用电感耦合等离子体原子发射光谱仪（ICP-AES）法测定双（乙腈）二氯化钯中的微量铅、镍、铜、镉、铬、铁、铂、金、铑杂质元素含量。选择合适波长消除光谱干扰,用背景点扣除的方式消除钯对杂质元素的基体干扰。各杂质元素的检测范围为0.001%～0.015%,加标回收率为91.15%～102.7%,精密度（RSD）为0.69%～8.33%。与直流电弧发射光谱分析方法相比,准确度和精密度均得到提高,且操作简单。
A method for the determination of Pb,Ni,Cu,Cd,Cr,Fe,Pt,Au,Rh in bis（acetonitrile）dichloropalladium（Ⅱ） by ICP-AES was developed. The samples were digested by HNO_3 and HClO_4, then dissolved with HCl＋HNO_3. The matrix effects come from Pd were eliminated by background point correction. The determination range is 0.001%~0.015%, recoveries and RSD were 91.15%~102.7% and 0.69%~8.33%, respectively. Compared with DC arc emission spectrometry, this method is more accurate and precise, easy to operate.
