ICP-AES Determination of Platinum and Palladium in Ore Sample After Enrichment by Fire Assay
摘 要
矿样中铂和钯经火试金法富集后,所得贵金属合粒用硝酸溶解,用电感耦合等离子体原子发射光谱法测定试样中微量铂和钯的含量.对火试金法的试验条件进行了改进,结果表明:铂和钯的质量浓度均在30.0 mg·L-1范围内与其发射强度值呈线性关系.方法用于分析国家标准物质(GBW 07342),测定结果与标准值相符.
Abstract
Platinum and palladium in ore Sample was enriched by fire assay method,and the precious metals alloy obtained was dissolved by nitric acid.The contents of platinum and palladium in the sample solution were determined by ICP-AES.Linear relationships between values of emission intensity and mass concentration of Pt and Pd were kept in the range within 30.0 mg·L-1.The proposed method was used in the analysis of a CRM (GBW 07342),the results obtained were in conformity with the standard values.
