Adsorption organic compounds

Adsorption is, of course, of major importance in the inhibition of corrosion by organic compounds (adsorption inhibitors) that have the ability to adsorb strongly on the metal surface, thus impeding the dissolution reaction and reducing the corrosion rate. It follows that the coverage of a metal surface by adsorbed inhibitor can be evaluated from the relationship... 

The inner-layer capacitance of Cd faces increases as the atomic density decreases. It has been suggested that hydrophilicity increases in the order Cd(0001) < Cd(10T0) < Cd(llZO). The same order has been proposed on the basis of data on organic compound adsorption.153... 

The Wheeler equation seems to be very simple with only one adjustable parameter k. However it has been discovered that it is difficult to correlate to operating parameters, mainly the flow rate Q. In addition, research conducted in other fields of adsorption such as volatile organic compounds adsorption for air purification, have shown that the breakthrough front is usually not symmetrical. In this case, it is useless to try to correlate k. ... 

Correlation of the parameters of heterogeneous surface active sites or its distribution functions on these parameters with activation parameters of organic compound chemisorption on the oxides surface is required for establishment of the reaction mechanism (for example, SeI or SnI)- An approach for calculation of distribution functions of heterogeneous surface active sites on the donor, acceptor and polarization components of organic compounds adsorption energy using the nonlinear inverse gas chromatography... 

Experimental measurements yield the actual effect of pH upon the extent of organic compound adsorption. The model is defined by choosing values of A l, A" , and Kf (s = surface complex formation) that best represent the...

Fig. 15 Dependences of the difference A(AC ) for various alcohols on the interfacial parameter AX for various metals. The number of each plot is equal to the number of carbon atoms of given aliphatic compound (updated from Refs. (5, 71]). A(AC ) = AC — AC, where AC is the Gibbs energy of adsorption of an organic compound at a metal—electrolyte interface and AC is the increase of Gibbs energy of organic compound adsorption, caused by the addition of electrolyte into the solution.
