本文研究了在有尿素和/或白蛋白存在的模拟子宫液中，在pH5.0、6.3和8.0，有0.10、0.15和0.20个大气压的氧气压力和无额外氧气压力，温度为37°C，并进行1、3、7、15、21和30天的实验的铜腐蚀。使用吸光度测量来确定铜溶解速率。在pH值8.0和0.20个大气压的氧气压力下，铜的溶解最高，1天为674μgd− 1，30天为109μgd− 1。与尿素相反，白蛋白的存在加速了铜的腐蚀。
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°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, 674μgd−1for 1 day and 109μgd−1for 30 days. The presence of albumin, contrary to urea, accelerates copper corrosion.
