木质颗粒活性炭吸附Cr（Ⅵ）的工艺条件

Technological Conditions of Absorbing Cr(Ⅵ)by the Woody Granular Activated Carbon

本文分别从静态和动态实验对影响活性炭吸附Ｃｒ（Ⅵ）的主要因素如炭种、表面含氧官能团的类型和数量、预处理及Ｃｒ（Ⅵ）浓度、ｐＨ值、温度、接触时间、解吸方法和条件进行了探讨和研究，确定了木质颗粒活性炭吸附Ｃｒ（Ⅵ）的合理的工艺条件。

By means of the static state and dynamic state experiments,this article made an approach to thefollowing factors which affected to absorb Cr(Ⅵ)by activated carbon:carbon kind;type and quantity of sur- face oxygenated functional group;pretreatment and Cr(Ⅵ);pH value;temperature;contact time;and desorp-tion methods and condions. It determined the optimal technological conditions of absorbing Cr(Ⅵ)by thewoody granular activated carbon.
