| 中文摘要 | using the low cost of lawny grass to remove methylene blue (mb) from aqueous solution was evaluated in the batch process and the fixed-bed column. the mb adsorption capacity onto cg (grass modified with citric acid) was 301.1 mg . g(-1) biomass, which was almost three times than that of rg (raw grass). the equilibrium could be explained as pseudofirst-order kinetic processes, and equilibrium time was shortened to 20 min (cg) from 40 min (rg). the adsorption equilibrium followed the langmuir isotherm model. the desorption rate with 0.1 mol . l(-1) hcl was almost 90 %. regenerated cg was reusable with a little decrease (only about 3.38%) in its adsorption capacity during six repeated cycles. in the fixed-bed column, the breakthrough point of cg begins at 183 bv, which was much higher than that of rg (56 by). the elution process was achieved in a very small hcl volume. |
