摘要：

The speciation of Cl-, OH- and SO42- in synthetic sea water has been studied by potentiometric measurements (pH-metric and ISE-Na methods)and by literature data analysis, using a well tested complex formation model. Stability constants, together with distribution of hypothesised species in synthetic sea water, as a function of temperature and salinity, are reported. The speciation model proposed in this work is discussed on the basis of chemical and statistical considerations. Comparison with some literature sea water models is given.
