摘要：Activated carbon was developed from TyphaAngustata L, characterized and used for the removal ofRhodamine B from waste water successfully. Rhodamine B is one of the water soluble, basic red cationic Xantheneclass dyes, a common water tracer fluorescent. Batch adsorption experiments were carried out as a function ofPH,contact time, initial concentration of the adsorbate, adsorbent dosage and temperature. The experimental data wereanalyzed using the pseudo second order kinetic model. The equilibrium data satisfied by Langmuir Isotherm models.The changes in standard free energy (ΔGº), Standard Entropy(ΔSº) Standard enthalphy (ΔHº) were calculated. Thethermodynamic study has showed that the dye adsorption phenomenon onto AC-MnO2-NC was favorable, endothermicand spontaneous.
