Height equivalent to a theoretical plate (HETP), which is an important factor to determine separation performance, is experimentally obtained for lithium isotope separation by a circuit of continuous displacement chromatography. The values of HETP are related to the flow rates and concentrations of the displacement reagents. A new equation to estimate HETP is derived and shows good agreement with the experimental data. Diffusion in the resin is found to be the major resistance for the isotope exchange reaction, and liquid mixing in the columns also strongly influences the value of HETP.
