The treatment of wastewater containing middle or low concentration of phenol solution is a troublesome environment problem. In this study, tea was modified by FeCl3,AlCl3,FeSO4,and we studied the adsorption performance of modified waste tea leaves on phenol-containing waste water. FeCl3 is the best modifier, the second one is FeSO4, and the last is AlCl3. And the effects of the initial concentration, pH value, adsorption time, particle size, and temperature on adsorption capacity were investigated. Langmuir isotherm model was better to describe the isothermal adsorption of phenol. ©2014, ...
