Response surface method-driven design of experiments for the synthesis of fly a...
Silva, Ana P. F.; Natal, Ana Paula Silva; Baldo, Arthur Pietrobon; Silva, Adriano S.; Díaz de Tuesta, Jose Luis; Marin, Pricila; Peres, José A.The growing need for sustainable wastewater treatment solutions has led to exploring alternative materials to explore large-scale and reliable technologies. This study focuses on optimizing the synthesis of geopolymers based on fly ash using a Box-Behnken experimental design to enhance their adsorption efficiency for phenolic compounds, as gallic acid model pollutant which are widely found in wastewater leachin...
Plastic waste-derived carbon nanotubes: Influence of growth catalyst and cataly...
Roman, Fernanda; Silva, Adriano S.; Díaz de Tuesta, Jose Luis; Baldo, Arthur Pietrobon; Lopes, Jéssica Paula Marim; Gonçalves, Giane; Pereira, Ana I.Low-density polyethylene (LDPE) was used in this work to grow carbon nanotubes (CNTs) by chemical vapor deposition (CVD) over catalysts based on Ni, Fe and Al, synthesized either by co-precipitation (C) or wet impregnation (I) methods, with CNT yields in the range of 16–33 %. The morphology of the CNTs was directly influenced by the route used for the CVD catalyst synthesis, with co-precipitation-derived CVD ca...
Occurrence of micropollutants in surface water and removal by catalytic wet per...
Silva, Adriano S.; Zadra Filho, Paulo Cesar; Ferreira, Ana Paula; Roman, Fernanda; Baldo, Arthur Pietrobon; Rauhauser, MadeleineMonitoring campaigns of contaminants of emerging concern (CECs) in surface waters is of utmost importance in evaluating the anthropogenic impact on riparian ecosystems. Beyond identifying pollutants and threats, treatment solutions are also needed to mitigate the adverse effects caused by polluted water discharged into the environment. For years, grab samples have been used to assess water quality, but the resu...
Innovative permeable reactive barriers for the elimination of contaminants of e...
Baldo, Arthur PietrobonRapid industrialization and urbanization have led to significant environmental challenges, particularly the contamination of water bodies by contaminants of emerging concern (CECs) due to insufficient tertiary treatment in wastewater treatment plants (WWTPs). Pharmaceuticals like acetaminophen (ACT) and sulfamethoxazole (SMX), as well as phenolic compounds like gallic acid (GA), are persist and bioaccumulate, p...
