Use of wood sawdust Teca (Tectona grandis) modified with citric acid in the biosorption of Cd (II) and Pb (II)

Abstract: ResumoO crescente avanço industrial e populacional ocasionou maior produção de resíduos contendo metais potencialmente tóxicos, tais como os íons Cd (II) e Pb (II) que, quando lançados diretamente no ambiente sem nenhum tratamento prévio, contaminam o ecossistema. Uma alternativa economicamente viável para o tratamento de resíduos com metais tóxicos consiste na biossorção que pode ser realizada por meio da serragem de madeira de Teca (Tectona grandis), nas suas formas in natura e modificadas com ácido cítrico,… Show more

“…Several alternatives for the remediation of natural waters have been proposed, with a particular focus on ion exchange adsorption technologies. Among the methods used to decontaminate effluents containing potentially toxic metals, the use of low-cost adsorbents of animal and/or plant origin has stood out as an excellent alternative (De Sousa et al, 2023;Nascimento et al, 2016;Sousa & Oliveira, 2022).…”
