摘要

Results from chemical trapping experiments in micellar solutions containing 1.5-5 mM aqueous solutions of three didodecyl dicationic dibromide gemini surfactants with different methylene spacer lengths (12-n-12 2Br where n= 2-4 CH2 groups) gave quantitative estimates of the molarities of interfacial bromide (Brm) and water (H2Om), the fractions of free and paired headgroups and counterions, and the net headgroup charge. These ...
