A conventional and two high copper amalgams were tested in 0.5% aqueous solutions of acetic, formic, lactic and succinic acid. The corrosion behavior of the amalgams in the different solutions was evaluated by analyzing the soluble corrosion products using an atomic absorption spectrophotometer every month during a 6-month experimental period. The high copper amalgams showed a high dissolution rate in formic and lactic acid solutions from the initial stages of immersion when compared to the conventional. Later a marked decrease of the dissolution rate could be observed but it still remained at high levels. In acetic acid the amounts of elements dissolved from high copper amalgams were much less. Conventional amalgam released much smaller amounts of elements in almost all solutions tested except in the case of silver in lactic acid. Finally, in succinic acid solution, the amounts of elements dissolved were unexpectedly small considering the low pH of the solution and the dissolution rates of the amalgams in the other organic acid solutions.
在0.5%的醋酸、甲酸、乳酸和琥珀酸水溶液中对一种传统汞合金和两种高铜汞合金进行了测试。在为期6个月的实验期内，每月使用原子吸收分光光度计分析可溶性腐蚀产物，以此评估汞合金在不同溶液中的腐蚀行为。与传统汞合金相比，高铜汞合金从浸泡初始阶段起在甲酸和乳酸溶液中的溶解速率就很高。随后可观察到溶解速率显著下降，但仍处于较高水平。在醋酸中，从高铜汞合金中溶解出的元素量要少得多。除了在乳酸中银的情况外，传统汞合金在几乎所有测试溶液中释放的元素量都要少得多。最后，在琥珀酸溶液中，考虑到溶液的低pH值以及汞合金在其他有机酸溶液中的溶解速率，溶解的元素量出乎意料地少。
