摘　　要：研究了改性糠醛渣对镍离子的吸附性能。结果表明,改性糠醛渣对废水中镍离子的吸附在30 min达到平衡;在50 mL含20 mg/L的镍离子废水中,加入改性糠醛渣0.02 g时,对废水中镍离子的吸附量达到19mg/g左右;平衡吸附量与平衡浓度之间的关系符合Freundlich和Langmuir等温吸附方程所描述的规律。Adsorption properties of modified furfural residue for nickel ion was investigted. The results showed that the adsorption capacity of modified furfural residue for nickel ion in wastewater was reached to balance at 30 min. In the wastewater with volume of 50 mL and nickel concentration of 20 mg/L, the adsorption capacity of 0.02 g modified furfural residue for nickel ions was about 19 mg/g. Relationship between the equilibrium adsorption capacity and concentration was accorded with the Freundlich and Langmuir isothermal adsorption equation.
