Draw up an iron lanthanum modified bentonite adsorption isothermal, then carry on a data regression and synthesis with the Langmuir equation and the Freundlich equation. The result indicates two equations both to be able to give a good description about the adsorption effect which iron lanthanum modified bentonite has on the scarlet dye. Study iron lanthanum modified bentonite adsorption dynamics,and then draw up an iron lanthanum modified bentonite adsorption dynamics curve.
