The adsorption of crystal violet (CV) simulated wastewater on the fallen willow leaves has been investigated. The effects of adsorption oscillating time, fallen willow leaves dosage, pH value, temperature and so on were examined of CV adsorption on fallen willow leaves, respectively. The result shows that the fallen willow leaves adsorbed the CV simulated wastewater well. The experimental data conformed to the Langmuir and Freundlich isotherm equations. The maximum biosorption capacity is 312.5 mg/g at 298K, which is superior to most reported biosorbents.
