Oxide Formation at the Sulfide Film‐Copper Interface in Anoxic Sulfide Solution and On‐Line Sulfide Detection Via Linear Polarization Resistance

Materials and Corrosion, EarlyView.
A flow through cell arrangement was used to examine the oxide formation at copper–copper sulfide interface in an anoxic, sulfide environment. Oxide formation on surface occurs because of exposure to aerated water during sample preparation. On‐line sulfide detection based on the linear polarization resistance of copper is also presented.
