Abstract

Copper pollution has caused serious public health problems recently, and activated Firmiana Simplex Leaf has proved effective to remove Cu(II) from aqueous solution. Factors affecting the adsorption of Cu(II) include: dosage, solution pH, temperature and duration. The thermodynamic behavior reveals the endothermic and spontaneous nature of the adsorption, and the max adsorption capacity calculated by Langmuir model is 66.721 mg g-1. The adsorption mechanism is further studied with the assistance of FT-IR test.
