摘要
采用4-氨基安替比林分光光度法测定苯酚的浓度,测定高沸醇木质素在不同浓度、不同温度和不同pH值的条件下吸附苯酚数据。结果表明,高沸醇木质素对苯酚的吸附量随着苯酚初始浓度的升高而升高,随着温度的升高而降低,随着pH值的升高而降低。高沸醇木质素和焦木素对苯酚的吸附比较表明,高沸醇木质素具有更好的吸附性能。利用高沸醇木质素的吸附性能处理含酚污水可以有效解决除酚问题,同时充分利用木质素资源。
The adsorptions of phenol by high boiling solvent (HBS) lignin were investigated in different conditions. The concentration of phenol was tested by 4-AAP(4-Aminoantipyrine) UV-Visible spectrophotometric methods. The adsorptions of phenol by HBS lignin were investigated in different conditions. The adsorbing effect is better in the condition of higher phenol concentration, lower temperature, or lower pH. By comparison with pyrolignin, HBS lignin has better adsorbing effect to phenol under the same adsorption condition. The adsorption property of HBS lignin is used to deal with phenol-water system. It is useful not only to remove phenol in the water, but also to extend the application of lignin resources.
