摘要
应用电感耦合等离子体质谱(ICP-MS)法测定地质样品中银时,锆、铌等元素干扰银的测定,造成准确度低、测定偏差大。采用银的富集、王水提取和化学分离法等方法可对干扰元素预分离,从而准确测定样品中银;而应用干扰校正方程及碰撞/反应池(CRC-ICP-MS)、膜去溶(DSN-ICP-MS)、激光剥蚀(LA-ICP-MS)和高分辨质谱(HR-ICP-MS)等新技术,能够更加方便、准确测定地质样品中银。
As we all know,results of determination of silver in geological samples by Inductively coupled plasma mass spectrometry(ICP-MS)were in low accuracy and large deviation of determination due to the interference of zirconium and niobium.Silver preconcentration,aqua regia extraction and chemical separation could solve the problem of interference.The interference correction equation and new techniques such as collision reaction cell-ICP-MS,membrane desolvation-ICP-MS,laser ablation-ICP-MS and high resolution inductively coupled plasma mass could be also applied to the determination of silver in geological samples,these methods were more convenient and accurate for the determination of silver in geological samples.
