Abstract
The rate of removal of heavy metal Copper ion (Cu 2+) from synthetic wastewater was studied using an ion exchange resin and pulsation technique. Variables examined were initial concentration of (Cu 2+), ratio of mass of resin to solution liquid volume, frequency, amplitude and geometry of the disc responsible for the pulsation motion. The results were presented mathematically by using the dimensionless analysis and the mass transfer correlation was obtained also Langmuir and Freundlich adsorption isotherms were examined where the date fits Freundlich adsorption isotherms more than Langmuir adsorption isotherms. It is concluded that percentage of (Cu 2+) removal decreases as initial concentration of (Cu 2+) presented increases and increases with contact time, frequency (rpm), amplitudes and mass of resin per unit volume of solution.
