ater contamination by the disposal of toxicmetals is recognized as aworldwide concern. Mercury is known

as relevant hazardous pollutant due to its toxicity and biomagnifications along the food chain, causing

serious impacts on environment and human health. A variety of processes are available for the treatment of

contaminated aqueous waste streams. Sorption processes are considered better alternatives because they are

easy to operate, economic and allow treating solutions with realistic concentrations. Among the different solids

for sorption processes, the synthetic sorbents such as the zeolite-type materials are very selective and present

high surface areas and great removal capacities. Niobium silicates, like AM-11 and NS91 and vanadium silicates

like AM-14, have showed excellent performances for Hg (II) removal. On the other hand, biological wastes from

agriculture and industry represent lower cost options for sorption operations. The biosorbents are largely avail-

able in nature and contain functional groups capable to bind the target metal in solution. They require few or

any chemical and thermal pre-treatments and may provide alternative options for water treatment and waste

management. Banana, potato peels, egg shells, Eucalyptus globulus bark and leaves, mushrooms and water

hyacinth etc., are examples of efficient biosorbents applicable in this work. The right choice for each process is

not a trivial task. In line with one of the goals of 2030, Agenda for Sustainable Development of United Nations,

which promotes the improving of water quality by reducing water contamination and foments an enhance in

wastewater treatment, this work encourages the safe water reuse by investigating and evaluating new efficient

and viable sorbents for the application in remediation processes for mercury removal.

Fabre E has completed her Degree in Chemical Engineering at Federal University of Santa Catarina, Brazil. She is a PhD student in

Chemical Engineering at University of Aveiro, Portugal and engaged in research and publications about sorption processes for

water treatment. She has worked with the search of innovative materials for the purpose of metals removal under environmental

realist conditions for real applications in line with the concept of circular economy. She is member of the associated laboratory

CICECO–Aveiro Institute of Materials which is the largest Portuguese Institute in the field of Materials Science and Engineering and

she is also member of the associated laboratory CESAM–Centre of Environmental and Marine Studies.
