Abstract
The River Nile and its branches are the main source of fresh water in Egypt. They are
subjected to all pollution sources, among and most important of it is the industrial
one. This study aims to investigate removal efficiency of industrial wastewater
discharged to Ismailia Canal using cement kiln Dust (CKD) and electric arc furnace
dust (EAFD) as industrial adsorbents. Some heavy metals such as; iron, manganese,
aluminum, nickel, and zinc have been studied. The adsorption process is examined in
terms of its equilibria and kinetics. Batch adsorption experiments are performed to
evaluate the removal of these metals onto CKD and EAFD by-product wastes under
various operational conditions such as; adsorbate ions concentration, contact time,
pH, adsorbent dose, and temperature. The results revealed that CKD has a very high
affinity to adsorb iron, manganese, nickel, and zinc ions. While, EAFD can efficiently
adsorb only manganese, aluminum and nickel. The adsorption isotherms and kinetic
studies indicated that the adsorptive behavior of heavy metals ions on CKD and
EAFD satisfy the Langmuir assumptions, i.e. monolayer formation on the surface of
the adsorbent, and obeys the pseudo-second-order equation reaction.
