| 摘 要： | 以甲醇为稀释剂,用电感耦合等离子体质谱法快速测定稀土示踪剂中17个稀土元素。研究表明,在优化的稀释剂甲醇浓度为2%(体积分数)、pH<2.47的条件下测定稀土元素,方法精密度(RSD)为1.23%~2.83%,日间6次测定的精密度为2.25%~4.76%,各稀土元素线性关系良好,检出限为2.0~9.0 ng/L;17个稀土元素的加标回收率为85%~108%,满足痕量元素分析要求。 |
| 关 键 词： | 稀土元素 井间示踪剂 电感耦合等离子体质谱 痕量元素分析 |

| Abstract: | A method for rapid determination of 17 rare earth elements in inter-well tracers was established with methanol as dilution reagent.The diluting solution was optimized as containing 2% methanol and pH<2.47.Under this optimized condition,the detection precision was 1.23%~2.83%RSD and the inter-day precision in six days was 2.25%~4.76%RSD.The linear relationship for all rare earth elements was perfect with detection limits of 2.0~9.0 ng/L.The spike recoveries for 17 rare earth elements were 85%~108%,which satisfied with the demands for trace amount of rare earth element determination. |
| Keywords: | rare earth element inter-well tracer inductively coupled plasma-mass spectrometry trace element determination |
