Abstract
Copper scales formed over 6-months during exposure to ground, surface and saline waters were characterized by EDS, XRD and XPS. Scale color and hardness were light red-brown-black/hard for high alkalinity and blue-green/soft for high SO 4 or Cl waters. Cl was present in surface or saline copper scales. The Cu/Cu 2O ratio decreased with time indicating an e transfer copper corrosion mechanism. Cu 2O, CuO, and Cu(OH) 2 dominated the top 0.5-1 A° scale indicating continuous corrosion. Cu 2O oxidation to CuO increased with alkalinity, and depended on time and pH. Total copper release was predicted using a Cu(OH) 2 model.
