摘要
质控样品作为最有效的质控手段之一被广泛应用于化学分析中.为保证金矿石中多元素检测结果的准确性和有效性,本工作设计并研制了一种金矿石质控样品,对金、银、铜、铅、锌进行了定值.该金矿石质控样经样品制备、均匀性检验及稳定性检验,火试金-原子吸收光谱法和酸消解-原子吸收光谱法定值,数据准确可靠,不确定度评定合理.与同类质控样品相比,具有元素种类多、含量范围广的特点,可为金矿石样品中相关元素的准确测定及量值溯源提供技术支撑.
Abstract
Quality control sample is widely used in chemical analysis as one of the most effective quality control methods.To ensure the accuracy and effectiveness of multi-element detection results in gold ore,a gold ore quality control sample was designed and developed in this work,and the values of gold,silver,copper,lead,and zinc were determined.The proposed gold ore quality control sample has undergone sample preparation,homogeneity tests and stability tests.Then,the fire assay atomic absorption spectroscopy and acid digestion atomic absorption spectroscopy are used to determine the value.The determined values are accurate and reliable,with reasonable uncertainty assessment.Compared with similar quality control sample,it has the characteristics of multiple types of elements and a wide range of content,which can provide technical support for the accurate determination and traceability of related elements in gold ore samples.
