Abstract

In recent years, there has been growing interest in finding inexpensive and effective adsorbents such as tea waste, wood, sawdust, kaolin, bentonite and peat. Sawdust is one of the promising adsorbents for removing dye pollutants from wastewaters. In this paper, the modified camphor sawdust is obtained from camphor sawdust with 5% cetyltrimethyl ammonium bromide solution activation. Then, the pore structure characteristics and adsorption dye wastewater in the aqueous solution capacity of the camphor sawdust were investigated. The kinetic and isotherm adsorption of dye wastewater by the camphor sawdust modified with surfactant are discussed in detail. The dye Congo red was chosen as the dye wastewater. The equilibrium data were better represented by Langmuir isotherm model than done by the Freundlich isotherm model. The adsorption process of the modified camphor sawdust for dye Congo red is homogenous. The maximum adsorption capacity obtained from the Langmuir isotherm is 125.39 mg/g.
