Abstract
The continuous experiments were carried out using fixed-bed column packed with strong-acid cation exchange resin for the removal of lithium ions from aqueous solution. The parameters such as bed height, flow rate and inlet concentration were investigated. Breakthrough time ($t_{0.05}$), saturation time ($t_{0.95}$), and total amount of lithium ion removed (mtotal) were obtained from the breakthrough curves. The results showed that $t_{0.05}$ and $t_{0.95}$ decreased with decreasing bed height, and decreased with increasing inlet concentration and flow rate. mtotal increased with increasing inlet concentration and bed height, but decreased with increasing flow rate. Thomas model and Yoon-Nelson model equations were applied to the experimental data, the results showed that the breakthrough data gave a good fit to Thomas model equation.
