摘　　要：发射光谱法和电感耦合等离子体-质谱法（ICP-MS）测定地球化学样品中的钼，两种方法的检出限、精密度和准确度均能满足地球化学普查质量要求。相对发射光谱法，ICP-MS的校准曲线线性范围宽，灵敏度、精密度、准确度高，分析步骤简单，干扰因素少，重现性好，测得的数值更可靠，更适合钼元素的分析．Determination of molybdenum in geochemical samples respectively using emission spectrometry and inductively coupled plasma - mass spectrometry （ICP-MS） was presented in this paper, Detection limit, precision and accuracy of two methods can satisfy quality requirements of geochemical reconnaissance. Compared with emission spectrometry, ICP-MS method has many advantages such as more wider linearity range of standard curve, better sensitivity, precision and accuracy, besides that simpler analytical procedure and fewer interference factors. Therefore, ICP-MS is more suitable to measure molybdenum.
