Anion analysis with x ray fluoresence
Abstract
The present thesis is proposing a new method of analysis of chemical speciation and elemental detection with environmental significance by using anion selective membrane and analyzing them with TXRF. Specifically this method include the production and application of a mechanism of chemical speciation of elements of periodic table that due to their different form have different toxicity, bioavailability and effect on living organisms. Also a qualitative and quantitative detection of chemical elements is presented that have anionic form in water solutions. The above procedure is accomplished by the use of anion selective membrane, an analytical tool which allows the selective bound of the desirable element on a membrane polymer matrix. This polymer structure is immobilized on a quartz that have been enriched with certain chemical reagents which provide the membrane with anionic activity and selectivity towards their ability to complex several elements. Typical examples that are examined ...
