Thermodynamic parameters for the binding of sulfate by open chain polyammonium cations.


The interaction of sulfate with some open chain polyammonium cations was quantitatively studied by potentiometric (H(+)-glass electrode) measurements. Enthalpy changes, for some systems, were determined calorimetrically. Some literature data were also considered in the discussion of results. In all the systems, A(SO4)Hi(i-2) species are formed (i = 1, ...m… (More)
