摘要
研究了从临汾褐煤中提取腐植酸后的残渣对Pb2+的吸附性能,结果表明随着pH的增大,吸附量不断增大;吸附曲线很好的符合Freundlich方程;热力学分析显示吸附反应具有自发性、吸热性和熵增特等特性。
The adsorption performance of the residue from Linfen Lignite after humic acid extraction for Pb2+ is studied. The result shows that the adsorptive capacity increases along with an increase in pH value; the adsorption curve agrees with Freundlich equation; the thermodynamic analysis shows that the adsorption reaction is characterized by spontaneity, heat absorption and entropy production.
