  • Title: Influence of pH and oxygen on copper corrosion in simulated uterine fluid.
    Author: Mora N, Cano E, Mora EM, Bastidas JM.
    Journal: Biomaterials; 2002 Feb; 23(3):667-71. PubMed ID: 11771686.
    Abstract:
    This paper studies the copper corrosion in simulated uterine fluids in the presence of urea and/or albumin, at pH 5.0, 6.3 and 8.0, with 0.10, 0.15 and 0.20 atmospheres of oxygen pressure and without additional oxygen pressure, at 37 degrees C temperature, and for 1, 3, 7, 15, 21 and 30 days experimentation. The copper dissolution rate was determined using absorbance measurements. Copper dissolution was the highest at pH 8.0 and 0.20 atmospheres of oxygen pressure, 674 microg d(-1) for 1 day and 109 microg d(-1) for 30 days. The presence of albumin, contrary to urea, accelerates copper corrosion.
