The sample preparation of copper for oxygen analysis is important due to the oxidation properties of copper. There are two methods of sample preparation that are frequently used for the analysis of oxygen in copper. The standard method according to ASTM E2575 uses chemical etching to remove impurities from the surface of the copper.
Copper in clay minerals is more likely to be fixed by organic mineral complexes of carboxyl carbon and iron and aluminum oxides than by carboxyl carbon alone [28,29]. Therefore, it was observed from this study that the removal of organic matter in group A reduced its adsorption capacity, which meant that the bond bridge formed by …
