Adsorption of Nonionic Surfactants (CnEm) at the Silica-Water and Cellulose-Water Interface

Singh, Kuljeet; Notley, Shannon


The adsorption of nonionic surfactants to the silica-water and cellulose-water interfaces was studied using optical reflectometry (OR) and soft-contact atomic force microscopy imaging. The polyethylene oxide alkyl ethers C14E6 and C16E8 were shown to readily adsorb to both interfaces. The kinetics of the adsorption process as well as the equilibrium surface excess was determined using OR. In agreement with previous studies, the short headgroup surfactant C14E 6 adsorbed to a greater extent than...[Show more]
