Implications of the Selectiveness of Cu Chelators on Cu0, Cu(I)O and Cu(II)O Powders
The time and stoichiometric ratio dependence on dissolution of Cu from Cu(I)O and Cu(II)O and metallic Cu was investigated for a series of known Cu chelators. This was monitored by ICP-OES and UV-VIS. A notable difference in the rate of reaction for Cu(I)O vs Cu(II)O was observed and the impact of a copper adduct precipitating from solution discussed as this may present a redeposition issue for Cu surface cleaning. Additionally these chelators were found to selectively favour Cu0 and typically showed higher solution levels of Cu when exposed to the oxides.
