Synthesis and study of physical-chemical properties of expanded graphite

Abstract

One a of the most urgent problems in the field of ecological status assessment is developing of a single integral approach to the problem of environmental quality and, in particular, of water as well as the evaluation criteria of their quality.
In this study, natural graphite is converted to adsorbent, intended for the use in getting rid of oil stains. The microstructure and morphology of expanded graphite made of antitermal natural graphite were investigated by Raman spectroscopy and scanning electron microscope (SEM).

Innovative terminative process was discovered and investigated in the systems «graphite – reactantoxidant» – it is a direct oxidative conversion of graphite in TWG going through the sig formation of as unstable intermediate reactions thermolysis.

The study of graphite’s as sorbents of oil in Kazakh science and technology is very relevant and has will be used in future.
