- Abstract
The excessive discharge of dye wastewater present certain hazards to human health and the environment. The removal of dyes from the aquatic environment is vital necessary. In this paper, a quaternized bamboo fiber (QBF) was successfully prepared by radiation induced graft-polymerization and further modification. The QBF was characterized by thermogravimetric, infrared and scanning electron microscopy analyses. The adsorption of methyl orange dye (MO) by the QBF was studied under different conditions. The adsorption kinetic study indicated that the adsorption was followed by pseudo-second-order model and the saturation equilibrium was reached in 60 min. The adsorption isotherm was well obeyed the Langmuir model with a maximum theoretical adsorption capacity of 555.56 mg/g. The QBF can be effectively desorbed by 1 M HCl and reused. Therefore, the QBF prepared using the radiation technique can be potentially applied to the removal of MO dye in wastewater.
