近年来电感耦合高频等离子体原子发射光谱(简称ICP—AES)技术发展迅速,它最主要的优点是能准确快速同时或顺序测定多元素,不过,在分析化学中与经典的电弧和火花发射光谱相比,ICP—AES也有许多局限性。例如,仪器设备费用和操作费用较高,样品一般要预先处理成溶液,对某些元素的检出限较差,以及光谱干扰少不了多少。因而,从总体看,ICP—AES只是经典光谱法的发展和重要补充,它不应该,也不可能完全取代、排斥或否定经典光谱法。经典的电弧和火花发射光谱法在分析领域仍发挥着它的作用。如何改进方法,提高分析效率以适应大批量的化探任务,是分析工作者
In recent years, inductively coupled high-frequency plasma atomic emission spectrometry (ICP-AES for short) has developed rapidly. Its main advantage is that it can accurately and rapidly determine multiple elements simultaneously or sequentially. However, in analytical chemistry, the classical arc and spark emission ICP-AES also has many limitations compared to spectroscopy. For example, equipment costs and operating costs are high, samples are typically pretreated to solution, have poor detection limits for some elements, and little or no spectral interference. Therefore, in general, ICP-AES is only the development and important supplement of classical spectroscopy. It should not and can not completely replace, reject or negate the classical spectroscopy. Classical arc and spark emission spectroscopy still plays its part in the field of analysis. How to improve the method and improve the efficiency of analysis to meet the high-volume task of geochemical exploration is the analysis of workers
