Journal ArticleDOI
Steel wastes as versatile materials for treatment of biorefractory wastewaters.
Sara V. Santos,Camila C. Amorim,Luiza N. Andrade,Natália C. Z. Calixto,Andréia Bicalho Henriques,J.D. Ardisson,Mônica Maria Diniz Leão +6 more
TL;DR: The use of waste as an adsorbent was more efficient for treatment of the oil emulsion than the dye solution, and BOFS had higher total organic carbon removal efficiency than the other waste materials.
Journal ArticleDOI
Synthesis and characterization of new NaX zeolite-supported Nb, Zn, and Fe photocatalysts activated by visible radiation for application in wastewater treatment
Fernanda F. Brites-Nóbrega,Igor A. Lacerda,Sara V. Santos,Camila C. Amorim,Veronice Sluzarski Santana,Nádia Regina Camargo Fernandes-Machado,José D. Ardisson,Andréia Bicalho Henriques,Mônica Maria Diniz Leão +8 more
TL;DR: In this paper, the authors showed that Nb2O5 impregnation resulted in a synergistic effect with the zeolite matrix forming Nb 2O5/NaX with a bandgap of 2.9 eV.
Journal ArticleDOI
Degradation of ethylenethiourea pesticide metabolite from water by photocatalytic processes.
Sue Ellen Costa Bottrel,Camila C. Amorim,Mônica Maria Diniz Leão,Elizângela Pinheiro da Costa,Igor A. Lacerda +4 more
TL;DR: The mineralization of ETU in the absence of hydrogen peroxide has led to the conclusion that ETU transformation products are susceptible to photolysis by UV light.
Journal ArticleDOI
Feasibility study of the use of basic oxygen furnace sludge in a permeable reactive barrier.
Paulo Ricardo Frade,Luiza Notini,Sara V. Santos,Regina de Fátima Peralta Muniz Moreira,Mônica Maria Diniz Leão,Camila C. Amorim +5 more
TL;DR: A scheme of the chemical reactions responsible for remediation process including BOFS dissolution, Cr(VI) reduction and Cr(III) precipitation, and the suitability of using BOFS in a permeable reactive barrier is proposed.
Journal ArticleDOI
Spatio-temporal variations of water quality in Nova Ponte Reservoir, Araguari River Basin, Brazil
Cristiano Christofaro,Mônica Maria Diniz Leão,Sílvia Corrêa Oliveira,Déborah T. Viana,Camila C. Amorim,Marcela David de Carvalho +5 more
TL;DR: In this article, multivariate techniques, like cluster analysis (CA) and principal component analysis (PCA), were used to evaluate the spatial and temporal variability of surface water quality in a large neotropical hydroelectric reservoir (Nova Ponte Reservoir).
