“…(9). The relative k 1 /Γ ∞ and k 2 /Γ ∞ rate constant values are rather reasonable and their ratios are in good agreement with published data [6][7][8] for the adsorption of different surfactants at fluid interfaces.…”

“…Generally, the adsorption of surfactant molecules from a solution to a liquid/gas [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] or to a liquid/liquid interface [1,5,[16][17][18][19][20][21][22][23][24] occurs in two steps. Surfactant molecules are first transported from the bulk to the subsurface by diffusion (the subsurface is a liquid layer just below the interface, belonging still to the bulk).…”

“…Further, the adsorption kinetics of some aliphatic carboxylic acids and aliphatic alcohols [6][7][8][9], like 1, 9 nonane dicarboxylic acid and 1, 9 nonane diol [6], was studied at the air/water interface and described by Langmuir kinetics, considering the adsorption and desorption rate constants. Another example is related to the adsorption of some salts of fatty acids, like sodium laurate [10,11,13], sodium myristate [10,11], and sodium oleate [14], from aqueous solutions to the air/water interface, which was analyzed by means of diffusion controlled kinetics.…”

The adsorption kinetics of some local anesthetics, like dibucaine and tetracaine, and of stearic acid from bulk solutions at the oil/water interface was studied by using the pendent drop and ring methods. The anesthetics were dissolved in aqueous solutions (pH 2), and the fatty acid was dissolved in benzene, each biocompound at several different concentrations in bulk solutions. Kinetic equations for Langmuir mechanism of adsorption at oil/water interface were tested. The kinetic analysis shows that Langmuir kinetic approach describes the dynamic interfacial pressures within the limits of the experimental errors over a wide range of time and for different surfactant concentrations in bulk solutions. It is also concluded that this approach allows the calculation of the ratio of the adsorption and desorption rate constants of these biocompounds at the oil/water interface. Obtained results are in substantial agreement with earlier reported data for the surfactant adsorption as well as with their molecular structure.

This work considers the mechanistic features of sonochemical degradation of volatile (chlorobenzene) and nonvolatile (phenol) organic pollutants. The sonochemical degradation of pollutant occurs in two pathways: thermal pyrolysis and hydroxylation. By coupling experimental results to bubble dynamics model, we have tried to establish relative contribution of these pathways to degradation of two kinds of pollutants. It is revealed that degradation of volatile pollutants occurs primarily by thermal pyrolysis while hydroxylation is the predominant mechanism of degradation of nonvolatile pollutants. The simulation results also help explain some interesting trends observed in degradation with reaction parameters such as initial pollutant concentration and salt addition to solution. These parameters are found to influence both pathways of degradation that leads to enhancement in degradation. However, the extent of this influence on hydroxylation and pyrolysis pathways is different for phenol and chlorobenzene. This is attributed to different partitioning behavior and solubility of the two pollutants.
