Abstract
The interactions between trace elements and carbonates (CaCO3) in deio nized water have been evaluated. The behaviour of Cu and Mn was invest igated using spectrometric techniques, namely electron paramagnetic re sonance, plasma atomic emission and high resolution electron microscop y. The results obtained show that, for low concentrations (10(-4) mol dm(-3)), these metals do not form a precipitated phase on vaterite and cubic calcite, but they interact favourably with the CaCO3 structure leading to the transformation of vaterite into cubic calcite. Our inve stigations have resolved that these two metals can be used successfull y as probes to follow and control this crystalline transformation and to assess its extent with time.
