研究了压水堆主回路铁的模拟腐蚀产物在柠檬酸水溶液、过氧化氢水溶液、柠檬酸—过氧化氢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溶液中的溶解量随柠檬酸浓度的增加而增大，随温度的升高而增大，在60℃时不同pH值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℃时的溶解量比70℃与80℃时的低；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 cobalt 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 portion of the dissolved simulated corrosion product of cobalt in citric acid aqueous solution clearly increaees with a rise in citric acid concentration and is ten times above the corresponding value of iron. The portion of the products that dissolve is the largest at pH 3. ...
