Adsorption Behaviors of Ni~(2+) Ion on a New Spherical Cellulose Adsorbent from Aqueous Solutions

The study was conducted regarding the adsorption behavior of Ni2+ ion on a new spherical cellulose adsorbent from aqueous solutions by static way.And,the effects factors on the adsorption behaviors,i.e.,initial concentration of Ni2+,solution pH and temperature were investigated.Moreover,the desorption experiments were also conducted.It can be concluded that the optimum adsorption pH was 8.0.And,when the initial concentration of Ni2+ exceeded 235 mg/L,the adsorption capacity tended towards saturation.The recovery percentage reached 96.8% when 1.5 mol/L of HCl solution was used as eluant.
