中文摘要: 应用电感耦合等离子体质谱(ICP-MS)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、王水偏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。
Abstract:The interference of zirconium and niobium in the determination of silver in geological samples by Inductively coupled plasma mass spectrometry (ICP-MS) resulted in low accuracy and large deviation of determination,witch can be preseparated by means of silver preconcentration, aqua regia extraction and chemical separation. 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 were applied to the determination of silver in geological samples, these methods were more convenient and accurate for the determination of silver.
