Abstract :

The wood sawdust powder adsorbent from Corymbia citriodora was studied to remove the textile congo red dye (CR) in aqueous medium. The results showed that the higher adsorption rates of dye by sawdust assessment were observed at pH 4.0 and 7.0, stirring time at 5 minutes and 5.0 g of adsorbent mass. This adsorption system provided a maximum adsorption capacity of 0.523 mg/g using the Langmuir mathematical model. The results suggest that such adsorbent material is capable of removing congo red dye in aqueous medium. In addition, the present work provides another alternative for the use of wood dust residue from sawmills in Espírito Santo State, Brazil.
