Sažetak
The effect of salt on the behaviour of bovine serum albumin (BSA) in solution and on the interactions
between BSA and the weakly charged polyelectrolytes poly(allylamine hydrochloride)
and poly(dimethylaminoethylmethacrylate) was investigated by potentiometric titrations. Titrations
of pure BSA solution and of the BSA solution with the addition of polyelectrolyte were
performed in the presence of different salts. Three electrolytes having the same anion and a different
cation were used, lithium chloride, sodium chloride, and caesium chloride. The corresponding
base served as titrant. Experiments were performed at four electrolyte concentrations.
The titration curves showed a strong influence of ionic strength and the electrolyte type. The
cation effect was found to be in accordance with the Hofmeister series.
