摘要
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.
