摘要
提出了电感耦合等离子发射光谱法(ICP-AES)测定紫砂制品中铅、镉、铬、砷、锌、锑、铜、钴、镍、锰、钡、铝、铁13种元素溶出量的分析方法。采用优化的仪器工作条件,对分析谱线的选择等因素进行了研究,各元素线性相关系数r≥0.999,相对标准偏差(RSD,n=6)为0.62%~3.64%,方法操作简便、快速、准确。
A method for determination of Pb ,Cd ,Cr ,As ,Zn ,Sb ,Cu ,Co ,Ni ,Mn ,Ba ,Al and Fe released from Zisha wares by inductively coupled plasma emission spectroscopy (ICP‐AES) was proposed . The working conditions of the instrument were optimized and the appropriate analytical line of each ele‐ment was selected ,with good correlation coefficient r≥0.999. The values of RSDs (n=6) were found in the range of 0. 62% 3. 64 % .
