Soledad Cárdenas is Full Professor at the Department of Analytical Chemistry (University of Córdoba). Since 2016, she is the head of the Affordable and Sustainable Research Group. Her research interests have been deeply related to the synthesis and characterization of novel sustainable extractant phases to be exploited in sample treatment. The new materials include (ligno)cellulosic support which can be eventually modified with polymeric, nanostructured or composite layers. Recently, the analysis of the synthesized substrates by ambient mass spectrometry (either by direct infusion or paper spray) is under development. In the field of sample treatment, she is the coordinator of the national thematic network “Spanish Network for Sustainable Sample Preparation, President of the Sample Preparation-Specialized Group of the Spanish Society of Analytical Chemistry and member of the European Committee of the EuChemS-DAC Sample Treatment Study Group. Since January 2023, she is Editor of Analytical and Bioanalytical Chemistry.
