Zveme vás na přednášku Prof. Jeffersona Santose de Gois (Rio de Janeiro State University) na téma: Analytical strategies for detecting at ultra-trace levels in environmental samples, která se bude konat ve čtvrtek 15. 8. 2024 od 13 hodin v zasedací místnosti děkanátu v 5. patře.

Detecting at ultra-trace levels may be challenging, and expensive in some cases, requiring special instrumentation and good expertise of the analyst. Therefore, this talk will present straightforward alternatives for determining inorganic and organic substances at low concentrations aiming at high-sample throughput and minimum sample preparation (when possible). Moreover, I will show the infrastructure of Rio de Janeiro State University, from number to social activities.

Jefferson Santos de Gois currently lives in Rio de Janeiro (Brazil) and works at Rio de Janeiro State University (UERJ), where he holds a permanent position as a professor. He obtained his doctorate in Chemistry (2016) from the Ghent University (Belgium) and Federal University of Santa Catarina, UFSC (Brazil) performing research in Atomic Absorption Spectrometry (AAS), High-Resolution Continuum Source Atomic Absorption Spectrometry (HR-CS AAS), Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and isotopic analysis via multi-collector ICP-MS. His thesis focused on the development of methods for halogen determination and isotopic analysis, as well as the application of the methods in environmental studies. After receiving his PhD, he accepted a position at UERJ, where he expanded his research interests to the determination of organic compounds (by chromatographic techniques) and chemometrics (design of experiments, pattern recognition, and multivariate calibration). He currently coordinates the research group “Espectrometria atômica, Molecular e Métodos de Separação”, advising doctorate and master and undergraduate students from the Graduate Program in Chemical Engineering at UERJ. His current research projects involve the application of nanomaterials for method development and removal of pollutants from the environment, the development of analytical methods for trace-element and organic compounds determination, sample preparation methods, the development of chemometric methods for multivariate calibration and classification, as well as the design of experiments.
