Supported liquid membranes are recently spotlighted as a separation or purification technology of toxic or valuable metal ions in aqueous stream. There are two directions to improve supported liquid membranes; one is the development of liquid membrane to get the more effective power of adsorption, and the other is the application of liquid membrane to new processes.
To apply supported liquid membranes to packed column contained porous particle as a packing material, numerical approaches are performed firstly. In packed column the model equations have the first order wave equations with nonlinear adsorptive reaction and there are some numerical problems to be solved. One of those is the phenomenon of numerical dispersion.
In this study, the cascade model of batch adsorptive tanks is proposed to remove that and the method to get more efficient numerical solver is developed. This model is applied to the process of removing the copper(II) ions from the aqueous stream and the analysis of this system is obtained as that model explains the phenomenon in packed column very well.
