Abstract: Abstract of thesis entitled GRAPHITE FURNACE - CAPACITIVELY COUPLED PLASMA - ATOMIC SPECTROMETRY AND INDUCTIVELY COUPLED PLASMA - MASS SPECTROMETRY FOR THE DETERMINATION OF SILICA AND TRACE METALS IN WATER Submitted by Yu Tung Man for the degree of Master of Philosophy at The University of Hong Kong in December 2002 A newly-developed Graphite Furnace - Capacitively Coupled Plasma -Atomic Absorption Spectrometry (GF-CCP-AAS) method was used for the determination of trace silica in aqueous media. The sensitivity for trace silica determination was improved using the GF-CCP-AAS method when compared with traditional method, such as Graphite Furnace - Atomic Absorption Spectrometry (GF-AAS). An Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) method was also used to determine trace elements in drinking water and mineral water samples available in Hong Kong.The GF-CCP-AAS method was developed to meet the demand in the determination of silica for type E-3 and type E-4 high-purity water. The GF- CCP-AES (or FAPES) method with single sample injection was also developed to meet the demand in the determination of silica for type E-2 high-purity water. The detection limits for using the GF-CCP-AAS and FAPES methods are 7.2 ng/L and 3.5 xg/L respectively. The GF-CCP-AAS method can overcome chemical interference which occurs in conventional GF-AAS methods such as matrixes containing sodium chloride, sodium orthophosphate and sodium sulfate but not magnesium sulfate due to the high temperature as the result of using an CCP during atomization. The presence of plasma in the atomization step in GF-CCP-AAS was found to affect the silicon absorption signal. The effects of the solution volume, the peak shape, and the plasma background correction on the absorption signal of silicon using GF-CCP-AAS were studied. Procedures using the fast-drying pre-concentration step were developed, coupled with GF-AAS, GF-CCP-AAS and FAPES. The use of fast-drying pre-concentration GF-CCP-AAS and fast-drying pre-concentration FAPES was found to satisfy the requirements of total silica content in type E-1, type E-1.1 and type E-1.2 high-purity water. The detection limits of GF-CCP-AAS and FAPES coupled with pre- concentration were 0.46 p, g/L and 0.3 pg/L respectively. The extent of the destruction of the quartz and amorphous silica by the plasma was found to be dependent on the size of particles. Amorphous silica with particle size less than 2.5 microns is more completely destroyed by the plasma while quartz silica with particle size greater than 2.5 microns is more favorablydestroyed by the plasma. An ICP-MS method was developed for the determination of elements of concern as listed by the World Health Organization in drinking and mineral water. Different sources of mineral water can be distinguished using isotope ratio analysis under favourable conditions. Magnesium was shown to be the major chemical interference in ICP-MS analysis. Cadmium, antimony, copper nickel, chromium, manganese and uranium were found to show signal suppression in solutions containing magnesium concentrations higher than 30 mg/L.

Download or read book Laser Enhanced Ionization Spectroscopy written by John C. Travis and published by John Wiley & Sons. This book was released on 1996-04-19 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser-enhanced ionization (LEI) is a type of optical spectrometrythat employs photoexcitation to ionize atoms selectively. Over thepast two decades, this method--originally known as the optogalvaniceffect--has been the object of extensive worldwide research and thesubject of numerous papers and published articles. Until now,however, no single volume has presented this wealth of theory anddata in a cohesive and accessible form. Laser-Enhanced Ionization Spectrometry fills this gap in theliterature. It synthesizes vast amounts of information previouslyavailable only through scattered research papers and covers everyaspect of the technology, from underlying principles and theory tomethodology and applications. This book examines the state of theart of LEI, compares it with other methods, and demonstrates howlaser-enhanced collisional ionization is especially well suited toanalytical atomic spectrometry. The contributors to this collaborative effort--from Russia,Australia, Europe, and the United States--clarify terminology,explain the inner workings of LEI, and offer derivations for bothidealized forms and realistic approximations. They also analyze thecapabilities and limitations of this technique as an analyticalmethod, including instrumentation, sources of noise, limits ofdetection, interferences, and applications. After concentrating largely on flame LEI as the most commonly usedmethod to derive LEI measurements, the discussion moves to thedevelopment of nonflame technologies for LEI. There is alsoextended coverage of the relationship between LEI and laser-inducedfluorescence, including an examination of the interplay oflaser-induced ionization and fluorescence techniques in differentatomic and molecular reservoirs. Laser-Enhanced Ionization Spectrometry places understanding,usefulness, and practical applications ahead of detailedderivations. For practicing analytical chemists andspectroscopists, it offers a clear and uncluttered approach to acomplex subject, as well as a fresh perspective on a still-emergingtechnology. This book sums up the present understanding and state of the art oflaser-enhanced ionization (LEI)-a unique but underutilized tool foranalytical atomic spectrometry. LEI possesses the special abilityto ionize atoms selectively. The text focuses on the role of thistechnology in analytical chemistry, and covers both theory andapplications in one complete, self-contained volume. Carefully crafted by leading experts from around the globe, withcontributions under six key headings, Laser-Enhanced IonizationSpectrometry * Draws on hundreds of research papers to create a comprehensivereference for LEI * Describes in depth how ions are produced, and how a signal isgenerated and detected * Provides an extensive and up-to-date compilation of published LEIdetection limits * Emphasizes basic understanding and practical applications ratherthan detailed derivations * Discusses terms and definitions and clears up sources ofconfusion in the field * Offers up-to-date coverage of instrumentation and applications * Evaluates the usefulness of LEI as an analytical tool * Deals with questions of limits of detection, interference, andnoise * Devotes an entire segment to nonflame technologies for LEI * Extends the discussion to fluorescence techniques and how theycan be interrelated with LEI in various atomic and molecularreservoirs
