“…Following the pioneering work of Hofmeister, the same series has been observed in many other areas of science, ranging from electrochemistry, colloidal science [5,6], surfactant micellization [7], bacterial growth [8], surface and interfacial tensions [9,10], peptide bonds [11], microemulsions [12], etc. Recently, a theory was proposed that allows one to quantitatively predict the effect of Hofmeister ions on the surface [13][14][15] and the interfacial tensions [16,17] of electrolyte and acid solutions. In this paper we want to explore the effect that Hofmeister ions have on the interaction between cationic polyelectrolytes and a hydrophobic surface.…”
