Abstract
Following the previous reports on silver and tin, the solubility of casted copper was measured by means of an atomic absorption analyzer. Three factors (solution, time and temperature) were analyzed by design of experiment.
The factors selected were all highly significant.The kind of solution played the most decisive factor:the most dissolution was revealed in the case of 1% lactic acid solution, the highest amount of dissolution was estimated approximately 0.5 g/cm2 after 3 months.No significant periodic and thermal effects were observed in the artificial saliva, while the thermal effect at 60℃ was noted in NaCl solution.The significant effects of both factors were revealed in 1% lactic acid solution.
