Heavy Metals Removal from Wastewaters by Sorption Processes Abstract. The habilitation thesis presents the most significant results of the researches oriented towards polymeric materials (organic synthetic resins and polyurethane foams) and waste materials as sorption media for heavy metal ions.

Removal of heavy metal ions from soils by electrokinetic treatment has several advantages. The extent of removal, however, is both soil specific and ion specific. The conditions to be maintained have to be established based on laboratory studies. With a view to maximize the removal of metal

Alfalfa has been found growing in fields irrigated with water high in heavy metal contamination [21, 22]. Studies have shown that alfalfa has tolerance levels to heavy metals above other plants [23-26].

Human activity introduces heavy metals (such as cadmium, arsenic and mercury) to our soils through mining, smelting, industry, agriculture and burning fossil fuels. Our disposal of materials containing heavy metals - a long list which includes paint, electronic waste, and sewage - also contributes to the burden of heavy metal contamination.

applied by metal finishing industries from several decades. In this process, metal ions from dilute solutions are exchanged with ions held by electrostatic forces on the exchange resin. The disadvantages include, high cost and partial removal of certain ions. For large quantities of competing mono and divalent ions Na (I) and Ca (II),

spectroscopy were used to determine the concentration of these ions.The obtained results reveal that the percent adsorption for removal of most ions at (pH 6.7, particle size less than 38 µm, and 3 min retention time) was approximately 90%.
