The monomer of methacrylic acid (MAA) was grafted on the surface of melamine-urea-formaldehyde (MUF) resin by using the redox initiating system formed by amino and persulfate, the grafted material MUF-g-PMAA was achieved. After carbonization at low-temperature, the carbonized material with more stable properties was obtained. The effects of temperature and pH value on the adsorption property of carbonized MUF-g-PMAA to Cu2+ were examined. The results indicated that the adsorption capacity of carbonized MUF-g-PMAA to Cu2+ reached up to 36.1 mg/g at pH=5.0 and 30℃. The adsorption capacity increased firstly and then decreased with temperature, and increased with pH value. Besides, the adsorption process conformed to the Langmuir adsorption isotherm model and pseudo-second kinetic equation.
