Results and discussion

Results:
Memo: A wide range of stability constants for the association of the substance with metal ions is available. These all show high values, suggesting that in the environment the substance will be associated with ions such as calcium and magnesium.

Any other information on results incl. tables

In order of complexation strength, values of the log10 of
the stability constants of representative metals with DTPMP
are:
Hg        22.6
Cu        19.5
Zn        19.1
Ni        19
Co        17.3
Cd        9.7
