摘要
重点介绍了目前比较常用的测定微量砷的方法及原理,包括:分光光度法、原子吸收法、原子荧光法、电化学法、电感耦合等离子体发射法,总结各种方法的最低检出限及其优缺点;最后,列举一些新兴测砷技术。通过总结这些方法,以求对实际应用有所帮助。
It focuses on the comparatively used determination method and principle of trace arsenic.The methods include spectrophotometer,atomic absorption,atomic fluorescence spectrometry,electrochemistry and inductively coupled plasms mass emission.The detection limits for trace arsenic are summarized respectively and the advantage and the flaw of each method is evaluated.Finally,It enumerates some newly technique about determination of trace arsenic.By summing up these methods,It will be helpful for practical applications.
