测定锂同位素组成的方法较多,晶体密度法是一种经典准确的测定方法。核磁共振光谱测定法,中子活化法及质谱法也已用于各种样品中锂同位素组成的测定,这些方法都需要相应的设备,都包括复杂的样品制备及仪器校准。研究原子吸收法测定锂同位素组成已有相当历史,自六十年代初就有人研究测定溶液中锂-6的原子百分含量,在一段时间里由于仪器的非线性响应在一定程度上限制了它的应用。随着仪器设备飞速发展,目前获得应用的测定锂
There are many methods to determine the composition of lithium isotopes, and the crystal density method is a classical and accurate method for determination. Nuclear magnetic resonance spectroscopy, neutron activation and mass spectrometry have also been used for the determination of lithium isotope composition in a variety of samples, all of which require corresponding equipment, including complex sample preparation and instrument calibration. There is a long history of studying the composition of lithium isotopes by atomic absorption spectrometry. Since the early 1960s, it has been studied to determine the atomic percentage of lithium-6 in solution. Due to the non-linear response of the instrument to some extent, it has been limited to some extent Applications. With the rapid development of equipment, the current application of lithium measurement
