Interactions between some phenolic compounds and macro-constituents of synthetic seawater (Na{sup +}, K{sup +}, Ca{sup 2+}, Mg{sup 2+}, Cl{sup {minus}}, and SO{sub 4}{sup 2{minus}}), at 20, 35, and 45 {per_thousand} salinity, have been investigated potentiometrically by using the [H]-glass electrode. The formation constants of phenol, o- and p-cresol, o-a dn p-nitrophenol complexes with sodium, potassium, calcium, and magnesium ions have been determined in the ionic strength range 0 {le} I {le} 1 mol/L. A comparison between the apparent protonation constants of phenols determined in synthetic seawater, and those simulated by a suitable complex formation model, is discussed. The possibility of calculating, by simulation, the apparent protonation constants of some chlorophenolic compounds in synthetic seawater is also reported.
