Abstract
Water is a country's major resource. However, with the increase in industrialization over the past 20 years, the risk of pollution has been increasing greatly. Because of the unselective discharge of industrial effluents, considered to be the major source of pollution in rivers, canals and other water bodies, the primary challenge facing most countries, and especially the developing countries, is to provide clean water. Due to the continual growth and development of our society there is an ever-increasing demand for clean water and better and more efficient water treatment methods are required. It isproved that Electro-coagulation has the capability to remove a large range of pollutants under a variety of conditions ranging from suspended solids (I>, heavy metals (Z.3>, petroleum products <4>, color from dye-containing solution (5>, aquatic humus (6J and defluoridation of water m.
Heavy metal ions are one of the main industrial pollutants. The aim of this project was to investigate the effect of current, types of electrode, pH, and types and concentrations of electrolyte on the removal of metals from aqueous solution by the process of Electro-coagulation. Electro-coagulation is the coupling of electrolysis with coagulation and is performed using an inert carbon cathode and a sacrificial metallic anode. Two types of sacrificial anodes were investigated, aluminum and steel. The investigations were carried out on nickel, copper and zinc ions' solutions of around 50ppm, lOOppm, 200ppm and 400ppm, respectively. Two electrolytes were investigated, KCI and NaCl, in concentrations of O.lmol/L, 0.2mol/L, 0.4mol/L and l.Omol/L.
