摘要
研究了压水堆主回路铁的模拟腐蚀产物在柠檬酸、过氧化氢、柠檬酸过氧化氢的水溶液中的溶解特性，结果表明：铁模拟腐蚀产物在柠檬酸水液中的溶解量随柠檬酸浓度增加而增大，随温度的升高而增大，在６０℃不同ｐＨ值时溶解量值的排列次序为ｐＨ３．５０＞ｐＨ４．００＞ｐＨ３．００＞ｐＨ４．５０＞ｐＨ２．３３；铁模拟腐蚀产物在Ｈ２Ｏ２水溶液中的溶解量远小于柠檬酸水溶液中的相应值，６０℃时溶解量明显小于７０℃、８０℃时的溶解量；共存的Ｈ２Ｏ２降低柠檬酸水溶液对铁模拟腐蚀产物的溶解量．
The studies on the dissolution characteristics of simulated corrosion product of iron on pressurized water reactor primary coolant loops in aqueous solution of citric acid,hydrogen peroxide and citric acid-hydrogen peroxide have been performed.The results show that the protion of the dissolved simulated corrosion product in citric acid aqueous solution increases with a rise in citric acid concentration and temperature.The portions of the pro ducts that dissolve at different pH values in 60 ℃ can be sized as pH 3.50>pH4.00>pH 3.00>pH4.50>pH2.33.it is shown that the portion of the dissolved simulated corrosion products in hydrogen peroxide aqueous solution is smaller that the corresponding value in citric acid aqueous solution,the portion in 60 ℃ is less than in 70 ℃ and 80 ℃,and that coexisting hydrogen peroxide reduces quantity of dissolved simulated corrosion products in citric acid aqueous solution.
