Guoy-Chapman theory

Debye and Hueckel s work is historically important to soil chemistry because their derivation was similar to that of Guoy and Chapman, published independently about 1910, who tried to predict the ion distribution in the aqueous solution around a charged surface such as a soil particle. Although the Guoy-Chapman theory and its... [Pg.78]

The potential arises from the difference in surface charges on the two sides of the two leaflets. A popular theory often employed is the Guoy-Chapman theory, which is based on a continuum model description of the solvent and employs the Poisson-Boltzmann equation. [Pg.184]

It is to be noted that there has been a cancellation between terms of order 1 and (1 - )/ to produce a term of order 1/f. The capacitance for the linearized Guoy-Chapman theory then yields... [Pg.165]

Figure 13.15 shows the charge density in an aqueous 1-1 electrolyte solution of molality equal to 0.010 mol kg at 298.15 K in the vicinity of a positive electrode with y>o = 10 mV, according to the Guoy-Chapman theory. [Pg.599]

Guoy and Chapman developed a theory of the charge distribution in the double layer about 10 years before Debye and Hiickel developed their theory of ionic solutions, which is quite similar to it. If one neglects nonelectrostatic contributions to the potential energy of an ion of type i with valence Zi, the concentration of ions of type i in a region of electric potential cp is given by the Boltzmann probability formula, Eq. (9.3-41) ... [Pg.597]
