【摘要】 <正> 在五十年代和六十年代,对贵金属冶金产品的分析多采用粉末、压丸、棒状的电弧激发技术。虽然上述诸法准确可靠,但是分析流程长,耗贵金属量多。采用化学分离富集试样中的待测杂质元素后,用ICP—AES法进行测定已见报道,但它有繁琐、分析时间长的缺点。用ICP—AES溶液法作钯的纯度分析,我们还未见报道。本文着重研究了钯基体对待测杂质元素的影响,拟定出一个ICP—AES法直接测定纯钯中十三个杂质元素,方法具有简便、快速、准确等优点。更多还原

【Abstract】 A method for determination of 13 impure elements in high pure palladium by ICP-AES has been developed. Sample is prepared in solution. It is necessary for this metheod to add matrix in standard. Relative error is less than 18%, RSD is less than ±9%. The method is simple, quick, accurate and can save a large amount of precious metals.更多还原
