Analytical Methods for the Determination of Mercury Species Using Cold Vapour Based Spectrometry: Application in Challenging Samples and Use of Nanoparticles as Photocatalytic Agents

Abstract

Analytical methods for the determination of mercury species using cold vapor based spectrometry : application in challenging samples and use of nanoparticles as photocatalytic agents / Jarol Ramon Miranda Andrades ; advisor: Ricardo photodegradation kinetics was also made by GC-CV-AFS, which confirmed the differentiated decreasing in concentration of Hg 2+ , CH3CH2Hg and CH3Hg (detected after propylation) during photo-degradation. The limit of detection of the method was 7 ng L-1 for Hg 2+ and CH3Hg and 10 ng L-1 for the CH3CH2Hg. Quantification was performed in a urine sample with certified values for inorganic mercury, which was also fortified with CH3Hg and CH3CH2Hg.
