Application Of Spectroscopic Techniques To The Determination Of Trace Toxic Elements

Atomic/molecular spectrometry is an important branch of analytical chemistry for the determination of elements. Up to now, the atomic spectrometry has become the most common and effective analytical methods for the determination of the contents of elements. On the other hand, although spectrophotometric elemental analysis is a traditional method, there have been some advanced studies, such as the work in this thesis which greatly enhanced the sensitivity of some heavy metals utilizing the characteristics of the long optical pathlength of a liquid core waveguide. Since most of the heavy metals are harmful to our environment or health, it is highly important to monitor them accurately and quickly. An atomic spectrometry performs excellently in the field of the determination of trace elements with its characteristics such as high sensitivity!There are three parts in this thesis: the first part is Chapter 1 in which the histories, principles and applications of various spectrometries were reviewed; the second part includes Chapter 2 and Chapter 3 and the analysis of the trace amounts of As, Cd, Pb and Zn by atomic spectrometry was discussed; Chapter 4 is the third part of the thesis in which the applications of the liquid core waveguide in molecular spectrometry was introduced. The atomic spectrometries utilized in this thesis...
