Özet

Vine stem js used as a low-cost adSdrbent foT the removal Of toxic dyes from the aqueOns solutions. In this study; the effects of electrolyte ectheentration,pH and type Of ionic species Otithe ZetaptetitiaIof the natural vine stein clisPerSkinS were inVestigatedby microelectrophoresis method. zeta-Potential experiments have been performed to deerininerthe point of zero charge (pze) and;potential determining ions (pdi).-Y.; The surf* charge of vine exhibited increasing negativity as the pH Of the solution hiereased. Vine steinrdispersions do not have pionit of zero charge:A gradual decrease in the zeta-potential occurs with the tnOnoValentelectrolytes when eonceitfration increased. Divalent and heavyrnetal electrolytes have h loss negative potentials dueto the higher valence of tons. The -potential values:have had a positiVe sign at trivalent electrolytes.
