Speciation of Trace Metals in Certain Groundwater in Egypt

Author(s): Nariman Hussein Mohamed Kamel

Several groundwater samples were analyzed in terms of drinking water quality, the groundwater samples were collected and tested for particle quality. The major elements and heavy metals in six groundwater samples were analyzed. A metal may be found in a number of different forms, such as soluble and/or complex forms. The free metal activity has been shown to be the key factor in determining metal toxicity. MinteqA2 code version 3.0 is a geochemical code was used to compute distribution of the dissolved metals in a certain groundwater samples in Egypt.. Speciation of the metal; Ca, Mg, Na, K, Fe, Al, Sr, Co, Cd and Pb were calculated. Sr, Co, Cd and Pb are the most toxic metals. Concentrations of these metal are found exceed the standard limit values. The free of the metals Sr, Ca, Co, Cd. specie constitute the major part of the dissolved metal ions. Meanwhile most of Pb species were found as Pb-carbonate. The electrostatic adsorption of these metal ions was calculated at low ionic strength. The surface ionic charge and the electrical potential of binding the metal with the soil surface sites has been calculated.
