| Abstract: | 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. |
