Derval dos Santos Rosa is a research professor at the Federal University of ABC (UFABC). Bachelor (1984) and Bachelor (2002) in Chemistry, master’s in chemistry/science (1988) and PhD in Chemical Engineering (1996) from UNICAMP (Brazil). Postdoctoral fellow at the University of Brighton (UK) (2015). He worked as Project Coordinator, Section and Division Manager at the Telebrás Research and Development Center (1986-2001). Full Professor at Universidade São Francisco (1996-2008). He was Coordinator of the Bachelor of Science and Technology (2009), Adjunct Dean of Undergraduate Studies (2009-2010) and Dean of Undergraduate Studies (2011-2014) at UFABC. He coordinated several research projects (sponsored by CPqD-Telebrás, CNPq, FAPESP, CAPES and several companies) and transferred some technology developed to National Companies. He is a reviewer for several journals, and an ad-hoc Advisor to FAPESP, CNPq, FINEP, CAPES, and some Brazilian Universities. Participation in some editorial boards of international journals. Board Member (various terms) and Director of ABPol (2017-2019). He has given several plenary lectures/Keynotes/Round Table as a guest. He supervised dozens of final undergraduate/scientific initiation/dissertations/thesis and other works. He has 240 paper publications, 300 congress publications, 7 books, 39 book chapters and 5 patents.
Prof Rosa’s expertise is focused on Environmentally Friendly Materials, leading to:
Contamination of wastewater with heavy metals (now called toxic potential elements – PTE) from industrial processes is an alarming problem in treating these wastes because they can cause serious health problems in living beings, such as genetic and physiologic diseases, even at low concentrations. Therefore, the need for techniques and processes to remove heavy metals from water emerges. Among those techniques, adsorption stands out because it is easy to implement, environmentally friendly, and inexpensive. With the advent of nanoscience, the development of nano-adsorbents, such as aerogels, can increase the removal efficiency of these metals and their ions. To intensify this effect, polysaccharide aerogels of the starch, chitosan, and cellulose may enhance their properties by adding various additives, such as cellulose nanostructures (CNSs), clays, and others that can alter the sorption properties of the metals present in the residual water. We will present recent results of studies developed by the researcher involving different polysaccharide aerogels and highlight the effects of various additives on the absorption of different divalent ions (cadmium, copper, manganese, nickel, and zinc) and chromium VI.
