“…used in the buffer solution. Sexsmith and White (1959) proposed an ion-pair adsorption mechanism for quaternary ammonium compounds whereby the surfactant counter-ion (anion) is adsorbed along with the surfactant into cellulosic materials in the vicinity of the CMC of the surfactant. Adsorption of Cl -followed this pattern in all samples used in this study (Figs.…”

“…Once the adsorbed ions reach a certain critical concentration, they begin to associate into two-dimensional patches (hemimicelle or admicelle) or three-dimensional patches (micelle or admicelle) of ions in much the same way as they associate into three-dimensional aggregates to form micelles in bulk solution (Garcia-Prieto et al 2007;Gu and Rupprecht 1990;Harwell et al 1985;Somasundaran et al 1964). Therefore, the adsorption between surface-active species and the solid surface at a low concentration can be derived by electrostatic interaction, van der Waals interaction, or ion exchange reaction and the surfactants are also adsorbed at higher concentration through the hydrophobic interaction between the adsorbed surfactants (Biggs et al 2007;Gu and Rupprecht 1990;Huang et al 2006;Paria and Khilar 2004;Somasundaran et al 1964;Sexsmith and White 1959).…”

The adsorption of alkyl dimethyl benzyl ammonium chloride (ADBAC) on wood was investigated. The changes in zeta potential curves of wood and ADBAC adsorption with increasing ADBAC concentration were highly correlated and showed two different mechanisms for ADBAC adsorption on wood: ion exchange reaction at low concentration and additional aggregation form of adsorption by hydrophobic interaction at high concentration. ADBAC adsorbed at a low solution concentration had high leaching resistance while ADBAC adsorbed into wood at above the critical micelle concentration (CMC) had low leaching resistance. The CMC decreased with addition of Mea, Cu-Mea, and buffer chemicals. The anion, Cl -of ADBAC was only adsorbed at solution concentrations above the CMC and was easily leached out. The adsorption isotherm of ADBAC on wood before and after leaching was fit to the Langmuir, BET, and Freundlich isotherm models; the BET and Freundlich models fit the adsorption isotherm well before leaching and the Langmuir and the Freundlich models showed better fits to the adsorption isotherm after leaching. The adsorption capacity of ADBAC into wood by cation exchange did not achieve the cation exchange capacity (CEC) of wood.

“…Salton (195 1) found that the adsorption of cetyltrimethylammonium bromide by six species of bacteria (including E. coli and Staph. aurew) was of the H2 type, but irregular isotherms have been noted for the adsorption of cationic surface-active agents by cellulose (Sexsmith & White, 1959) and anionic surface-active agents by cotton (Meader & Fries, 1952). Thus the irregular isotherms for the adsorption of iodine from the iodine : cetomacrogol complex may be related to the surface-active properties of the complex.…”

The uptake of iodine by baker's yeast, serum, E. coli and Staph. aureus from aqueous dilutions of an iodine non‐ionic surface‐active agent complex was compared with that from aqueous dilutions of an ethanol and potassium iodide solution. The form of adsorption isotherms depended upon the iodine system and the substrate. A characteristic of all isotherms was the high affinity at low iodine concentrations. Except where high ethanol concentrations remained, uptake was greater from the ethanol: potassium iodide dilutions. The pH of the iodine system also influenced the uptake, the effect varying with the iodine system and the substrate.

“…Cellulose derivatives and their adsorption properties have been studied extensively in the textile and paper industries. These studies have often involved dye and surfactant adsorption (2)(3)(4)(5)(6)(7). Cellulose, including microcrystalline cellulose, has also been used to coat TLC plates for use in the separation of various chemical and biological agents (8,9).…”
