| Abstract: | The apparatus for measuring the rising potential of CGA to rise through an aqueous solution was set up.Interfacial electrical properties and adsorption properties of CGA produeced by sodium dodecyl sulphate(SDS or NaLS)solution were investigated under various conditions(i. g.flow rate of CGA(Q_(CGA)),pH,the concentration of NaCl and SDS in aqueous solution).The rising potentials(U_f)of CGA in aqueous solution of SDS were measured.The electrokinetic adsorption densities of SDS in rising CGA surfaces were calculated from Zeta-potentials in terms of the Gouy-Chapman theory. |
