Preparation of Modified Expanded Graphite by KOH

Abstract:

A new material on adsorption of Pb(Ⅱ) was introduced in this paper. EG was modified by soaking in KOH. MEG (modified expanded graphite) was characterized by SEM, XRD and FTIR. The removal rate of Pb(Ⅱ) rose to 92.23% from 59.14% on MEG . And the adsorption quantity came up to 46.3869mg/g from 31.9662mg/g. All above shows that MEG has better adsorption performance.
