| Abstract: | The effect the porous structure of activated carbons obtained from furfural and coconut shells has on the kinetics of [Au(CN)2]? ion adsorption is studied. Effective diffusion coefficients for [Au(CN)2]? anions in transport and adsorbing pores and mass transfer coefficients in a transport system of the pores and in microporous zones are calculated using the statistical moments of the kinetic curve. |
