Coadsorption of Naphthalene Derivatives and Cetyltrimethylammonium Bromide on Alumina/Water, Titanium Dioxide/Water, and Silica/Water Interfaces

Adsolubilization of 2-naphthol into adsorbed layer of PEO–PPO–PEO triblock copolymers on hydrophilic silica

“…The amount of 2-naphthol adsolubilized into the adsorbed layer of P123, P103, and P105 increases with an increase of Pluronics concentration, shows a maximum, and then decreases with a further increase of the concentration. Similar behavior has been reported by many adsolubilization studies [9,10,[14][15][16][18][19][20][21][22][23]. The decrement in the adsolubilization amount is interpreted as follows: incorporation of the water-insoluble compound takes place not only into the adsorbed layer but also into the solution micelles simultaneously.…”

“…This phenomenon is called surface solubilization or adsolubilization [1]. The adsolubilization has been widely used in the development of various industrial products such as paints [2,3], pharmaceuticals [4,5], preparation of polymer thin films [6][7][8], and waste water treatment to collect and remove organic pollutants [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”

“…The adsolubilization behavior has been investigated systematically from the viewpoints of surfactant structure [9][10][11][12], kind of solutes [13,14], pH in solution [14][15][16][17], and surface properties [18,19]. For example, we selected two series of cationic surfactants for understanding an effect of surfactant structure on the adsolubilization.…”

Adsolubilization of 2-naphthol into adsorbed layers of triblock PEO–PPO–PEO copolymers on hydrophobic silica particles

“…Adsolubilization of solutes into adsorbed surfactant layers has been investigated as a function of surfactant structure [9][10][11][12], type of solutes [13,14], pH [14][15][16][17], and substrate type [18,19]. For this phenomenon to be applied in the industrial fields, however, the use of polymeric surfactants as an adsorbate is more practically important because replacement of the solution phase may cause desorption of the adsorbed surfactants away from the interface.…”

“…Incorporation of water-insoluble organic compounds (solutes) into the adsorbed layer sometimes takes place even if the solutes themselves hardly adsorb at the interface. This phenomenon is called surface solubilization or adsolubilization [1] and has been widely used in the development of various industrial products such as paints [2,3], pharmaceuticals [4,5], surface coatings with polymer thin layers [6][7][8], and wastewater treatment to collect and remove organic pollutants [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”
