木质素对废水中菲的吸附

[目的]研究木质素对废水中菲的吸附特性。[方法]通过木质素对废水中菲的吸附试验，考察缓冲液、温度、pH值、初始浓度、吸附时间等对于木质素对菲的吸附特性的影响。[结果]木质素对菲的吸附属于快吸附过程。在相同温度下，木质素对菲的吸附在酸性和中性环境下变化不明显，在碱性环境下对木质素吸附菲有明显的促进效果；在相同初始pH值条件下，木质素对菲的吸附作用随温度的升高而增强，且这种影响随pH值的升高逐渐增强。f结论]木质素对菲具有较强的吸附能力。

Adsorption of Phenanthrene in Wastewater by Lignin

[Objective] The research aimed to study the lignin adsorption patterns of phenanthrene.[Method]In the adsorption experiments in wastewater,background liquid,temperature,pH value,concentrations,adsorption time were investigated as the effective parameters on the adsorption characters.[Result]The adsorption of phenanthrene by lignin was the quick adsorption.The change of pH value had no evident influence on the adsorption characters in the acidic condition,but had positive influence obviously with the pH valu...
