摘要
目的:建立电感耦合等离子体原子发射光谱法(ICP-AES法)同时测定药用玻璃包材的砷、锑、铅、镉浸出量。方法:样品浸出液直接用电感耦合等离子体原子发射光谱仪测定。结果:标准曲线线性良好,相关系数在r在0.99996~0.99998之间,方法的检出限砷、锑、铅、镉分别为0.0228mg/L、0.0072mg/L、0.0039mg/L、0.0006mg/L,样品浸出液加标回收率砷、锑、铅、镉分别95.0%、97.4%、95.2%、94.4%,相对标准差在2.3%~4.8%之间。结论:方法准确、简便、快速。
ICP-AES method for the simultaneous determination of As、Sb、Pb、Cd,released from drug glass containers was presented. Sample solution was directly determined by ICP-AES. Good linearity was obtained and related coefficient from 0.99996 to 0.99998. The detection limit was from 0.0006mg/L to0.0072mg/L. The recovery rate of standard in sample solution was from 92.4% to 97.4%,RSD was from 2.1% to 4.8%. The method is precise simple and fast.
