Interfacial concentrations of chloride and bromide in zwitterionic micelles with opposite dipoles: Experimental determination by chemical trapping and a theoretical description

► Anion concentrations in zwitterionic micelles determined by chemical trapping. ► Poisson Boltzmann description used to fit experimental anion concentrations in zwitterionic micelles. ► Assuming translational freedom of ions in the micellar adsorbing plane gives the best description.
