Adsorption performance of food red 17 dye using an eco-friendly material based on luffa cylindrica and chitosan
R. Schio, Rejiane da; DA BOIT MARTINELLO, KATIA; Netto, Matias S.; O. Silva, Luis F.; Mallmann, Evandro S.; Dotto, Guilherme Luiz (ElsevierNetherlands, 2021-11-22)Luffa cylindrica (LC), a lignocellulosic material coveted for its versatility, was investigated to immobilize crosslinked chitosan and remove Food red 17 (FR17) dye from aqueous solutions. LC/chitosan was crosslinked with ... -
Effects of atmospheric pollutants on human health and deterioration of medieval historical architecture (North Africa, Tunisia)
O. Silva, Luis F.; S. Oliveira, Marcos L; Neckel, Alcindo; Stolfo Maculan, Laércio; Milanes, Celene B.; Bodah, Brian W.; Cambrussi, Laura; Dotto, Guilherme Luiz (Elsevier BVNetherlands, 2022-01)Air pollution is a factor of concern on a global scale, accelerating the deterioration of historic medieval architecture and having harmful effects on human health. The general objective of this study is to understand the ... -
