A、There are two main approaches to the evaluation of trace metal speciation-experimental measurement and computer modelling.
B、The experimental determination of speciation is hampered by a number of problems, such as sensitivity, disruption of the labile equilibrium of the system. Besides, it is tedious and time consuming .
C、The main shortcoming to the computational approach is the reliability of the data used. The results of the model are only as good as the parameters on which they depend and any shortcomings in either the analytical concentration of the system under investigation or in the thermodynamic data will result in a very misleading speciation profile.
D、The major advantages of computer modelling is that changes to the model can easily be made and thus the effect of say a 10% error in one of the component concentrations can very readily be investigated. Similarly, stability constant data may be varied over a range in order to see if this has any effect on the speciation profile. This type of operation also serves to identify those species which are of major importance. Last but not least, it is very quick and can easily be repeated.
