Porous Chitosan-silica-polyethylene Glycol Membrane for Dynamic Adsorption of Binary Mixtures Cu(II) and Zn(II) Ions

F. Widhi Mahatmanti, Nuryono, and Narsito
Abstract—The adsorption of binary mixtures of Cu(II) and Zn(II) ions was studied using dynamic methods employing chitosan-silica-polyethylene glycol (Ch/Si/P) as adsorptive membrane. Ch/Si/P membrane was synthesized by blending rice hull ash (RHA) silica and polyethylene glycol into chitosan. Silica and polyethylene glycol blended into the Ch to improve the mechanical properties and the membrane porous. The membrane was characterized using mechanical properties test, scanning electron microscopy (SEM) and swelling test. Dynamic adsorption experiments suggested that the adsorption capacity depended on adsorbent morphology and differences concentration between the source phase and the stripping phase. Ch/Si/P membrane presented more affinity for Cu(II) than for Zn(II). The decrease of the amount of metal adsorbed onto Ch/Si/P membrane in binary system showed that the competition effects between two metal ions. The desorption was also investigated, Cu(II) and Zn(II) ions could be selectivity permeated using a process by water, HCl, and Na2EDTA solution as the stripping phase.

Index Terms—Chitosan, membrane, dynamic adsorption, Cu(II) and Zn(II).
