| Abstract: | Commercially nanoScerium oxide was treated with 0.05mol/L sulfuric acid. And the organics in the acrylic fiber wastewater were as adsorbates, The adsorptionSexperiments were performed at room temperature. The factors affecting theSadsorption capacity ofSmodifiedSnano cerium oxide on organicSwere research, The optimumSadsorptionSconditions were 0.25g modifiedSnano cerium oxide, solution pH value was 7.5, stirring adsorptionStime 3h, The adsorptionSremoval rate of COD reached more than 60%. The adsorptionSof modifiedSnano cerium oxide onSorganicSaccords with Freundlich isothermal adsorptionSmodel, Sthe adsorption process accorded withSquasi twoSlevel dynamics equation under room temperature. |
