摘要
应用电感耦合等离子体-原子发射光谱法测定银中铝、金、钡、铋、钙、钴、铬、铜、铁、锂、镁、锰、钼、镍、铅、钯、铂、锡、钛、钒、钇及锌22种微量杂质元素。试液浓度为10mg/mL时,测定范围为10—320μg/g,回收率在94.9%—107%之间,相对标准偏差在3.3%—8.7%之间(n=6)。
The twenty-two trace impurity elements of AI,Au,Ba,Bi,Ca,Co,Cr,Cu,Fe,Li,Mg, Mn, Mo, Ni, Pb, Pd, Pt, Sn, Ti, V, Y and Zn in silver are determined by ICP-AES. The range of determination was between 10--320μg/g in the sample concentration of 10mg/mL. The recovery is between 94.9 %--107 % with the relative standard deviation of 3.3%--8.7% （n=6）.
