  Abstract

Desorption characteristics for ions adsorbed onto sericite was performed by means of HNO3 solution which was selected as the best desorbing agent in the previous work. Elution of nickel ions adsorbed onto sericite using HNO3 solution was confirmed by means of scanning electron microscopy (SEM) & energy dispersive X-ray spectroscopy (EDX) analysis. Desorption efficiency for nickel ions was 100% at the 20 mM of concentration. Also, nickel ions was completely desorbed within 1.0 of S/L (mg/mL) ratio which is defined as the ratio of adding amount of adsorbent and volume of desorbing agent and desorption process was quickly carried out within 60min. Finally, removal efficiency of reused sericite for nickel ions was constantly maintained until the 4th cycle.
