An approach to textile dye removal using sawdust from Aspidosperma polyneuron
(2017-01-02)
The textile industry is responsible for discarding wastewater contaminated with dyes. The timber industry generates waste in the form of sawdust. The aim of the present study was to evaluate the adsorptive potential of ...
Kinetic and Thermodynamic Studies on the Adsorption of Reactive Red 239 by Carra Sawdust Treated with Formaldehyde
(MULTI-SCIENCE PUBL CO LTDBRENTWOOD, 2012)
In this study, carra sawdust pre-treated with formaldehyde was used to adsorb reactive red 239 (RR239). The effects of several experimental conditions, including the concentration of dye, sorbent dosage, temperature, ionic ...
Immobilization of Zn(II) ions from contaminated biomass using ceramic matrices
(Elsevier Science, 2019-07)
This article describes the adsorption of zinc ions from synthetic solutions using residual pine sawdust as an adsorbent and, subsequently, the use of clay ceramic pieces and contaminated biomass as metal immobilizers. The ...
Estudo da utilização de serragem de madeira como adsorvente para o tratamento de efluentes têxteis
(2010)
The Brazilian textile industry has been a highlight in the global economy. Connected with this high economic performance there is the water consumption and the generation of great volumes of wastewater which present high ...
Sawdust Derivative For Environmental Application: Chemistry, Functionalization And Removal Of Textile Dye From Aqueous Solution
(Academia Brasileira de CiênciasRio de Janeiro, 2016)
Recuperação de reservatórios eutrofizados por atividades antrópicas : estudos em microcosmos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-05-25)
The economic development of a country depends on good quality of water
available, so the conservation and restoration of water bodies are strategic
conditions for this to happen. However, water resources have become ...
Removal of Zn(2+) from Electroplating Wastewater Using Modified Wood Sawdust and Sugarcane Bagasse
(ASCE-AMER SOC CIVIL ENGINEERS, 2009)
This paper describes the preparation of new adsorbents derived from sugarcane bagasse and wood sawdust (Manilkara sp.) to remove zinc (II) ions from electroplating wastewater. The first part deals with the chemical ...
Adsorção de azul de metileno em solução aquosa com pó de serragem de Erisma uncinatum Warm
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEngenharia CivilUTFPR, 2016-12-02)
The quantity and diversity of dyes present in industrial textile effluents discharged into the water bodies generate negative impacts on the environment. Therefore, it is necessary to carry out treatments in order to ...
Degradation and adsorption of AZO RR239 dye in aqueous solution by nanoscale zerovalent iron particles immobilized on sawdust
(IMPRENTA UNIV ANTIOQUIA, 2010)
Carra sawdust pretrated with formaldehyde was used to adsorb RR239 (reactive azo dye) at varying pH and zerovalent iron (ZVI) dosage. Modeling of kinetic results shows that sorption process is best described by the ...
