Continuous column adsorption of lead (Pb) and cadmium (Cd) was studied using pH adjustment and calcium-saturated montmorillonite in a short stainless steel column. Changing either pH or Β―ow rate, while keeping inlet concentration of the ions constant, led to considerable changes in efΒ―uent concentra
A mathematical model is proposed and compared with experimental data for the migration of heavy metal ions (Pb and Cd) during the Β―ow of aqueous solutions through calcium-saturated montmorillonite packing. The main system parameters are pH, Β―ow rate and concentration. It is assumed that the liquid p
