摘　　要：为了准确获取地质样品中的元素含量信息,提出基于电感耦合等离子体质谱法的地质样品中铌和钽测定方法。按照测定需求,准备试验仪器并设定工作参数,根据试验需求准备主要试剂,制备地质样品标准溶液,接着进行样本分解、体干扰处理、内标选择以及设定检出限,从而完成地质样品中铌和钽的ICP-MS测定。测试结果表明,无论是铌元素还是钽元素,设计的10个不同组别中的测定结果均展现出了极高的准确性,其相对偏差均严格控制在4%以内。因此,说明所提出的测定方法在实际操作中具有稳定性和可靠性,可以实现对地质样品中金属元素的高精度测定。In order to accurately obtain information on element content in geological samples,a method for determining niobium and tantalum in geological samples based on inductively coupled plasma mass spectrometry is proposed.According to the measurement requirements,prepare the experimental instruments and set the working parameters.Prepare the main reagents according to the experimental requirements,prepare the geological sample standard solution,and then perform sample decomposition,body interference treatment,internal standard selection,and set the detection limit to complete the ICP-MS determination of niobium and tantalum in geological samples.The test results show that the measurement results of both niobium and tantalum elements in the 10 different groups designed exhibit extremely high accuracy,with relative deviations strictly controlled within 4%.Therefore,it indicates that the proposed measurement method has stability and reliability in practical operation,and can achieve high-precision determination of metal elements in geological samples.
