✦ Synopsis

The removal of copper and nickel from aqueous solutions using a simple tank cell, an improved mass transfer inert fluidised bed cell (Chemelec) and a three dimensional high surface area cell are examined. The high surface area cells which were examined closely consisted of a packed graphite particle bed cell using two different sizes of particle. The packed bed cells were found to be extremely effective in reducing metal concentrations below 1 ppm. The effect of current density and flow rate were studied for each type of cell The most economic concentration range in which each cell should operate was determined. From this data suitable combinations of cells can be chosen to remove metal for high concentrations (20 000 ppm ) to very low concentrations ( < 1 ppm).
