#### **Monika Wawrzkiewicz**

Monika Wawrzkiewicz has been working as a professor in the Department of Chemistry, Faculty of Chemistry, Maria Curie-Sklodowska University in Lublin (MCSU) since 2016. She obtained her Ph.D. in chemistry (2005) and then habilitation (2015) at MCSU. She is a lecturer in inorganic chemistry for students of the Faculty of Chemistry at MCSU. Her research interests are sorption and separation of inorganic and organic compounds with particular emphasis on dyes and heavy metal ions on various sorbents, synthesis, and characterization of hybrid adsorbents and composites, as well as environmental protection. She is the author of more than 64 international peer-reviewed papers and book chapters. She is a member of the Polish Chemical Society and the European Chemical Society.

#### **Anna Wołowicz**

Anna Wolowicz is an assistant professor at the Department of Chemistry, Faculty of Chemistry, Maria Curie-Sklodowska University in Lublin (MCSU). She obtained her M.Sc. in Chemistry (2006) and Ph.D. in Chemistry (2010) from MCSU. Since then, she has continued her postdoctoral research on the evaluation of the sorption properties of various materials used to remove inorganic and organic pollutants from water and wastewater. Her research interests are in the sorption and separation of noble metals and heavy metals with a focus on ion exchange chromatography and environmental protection. She is the author of more than 38 international peer-reviewed papers and chapters in books. She is a member of the Polish Chemical Society and the European Chemical Society.
