水中痕量 Mo 的测定已有多种分析方法,诸如分光光度法、原子吸收光谱法、动力学法、石墨炉原子发射光谱法、中子活化分析法、电子顺磁共振谱法等。由于天然水中 Mo 的存在量很微,许多方法都必须经过预先使 Mo 与伴生干扰元素分离后方可测定。通常采用的分离方法有沉淀、共沉淀、共结晶、萃取、离子交换、活性炭吸附以及泡沫技术等。这些分析方法由于手续繁杂,或者使用的仪器过于昂 There are many analytical methods for the determination of trace Mo in water, such as spectrophotometry, atomic absorption spectrometry, kinetic methods, graphite furnace atomic emission spectrometry, neutron activation analysis, and electron paramagnetic resonance spectroscopy. Due to the small amount of Mo present in natural water, many methods must be determined beforehand by separating Mo and associated interfering elements. Commonly used separation methods are precipitation, co-precipitation, co-crystallization, extraction, ion exchange, activated carbon adsorption and foam technology. These analytical methods are complicated by the procedure or the instruments used are too high
