Abstract
Among the rare Earth elements Ce(III) is the most widely distributed in the Earth’s crust. Cerium is widely used in luminescence, pharmaceuticals and photographic industries, metallurgy, microelectronic, organic synthesis starting materials, scintillation counters, catalysts, glass additives, fuel additives , as one of the active components of catalytic converts in vehicles. Cerium is also used in agriculture, forestry and animal husbandry , and much attention is now being paid to the study of cerium in the environment. Addition of small amounts of the cerium to steel significantly modifies its properties, Therefore, the accurate determination of cerium at trace levels is important industrially. Cerium, like other rare Earth metals, has low to moderate toxicity. Fumes from cerium fire are toxic. People exposed to contain to cerium have experienced itching, sensitivity to heat and skin lesions. The animals were given large amounts of cerium, they died of cardiovascular collapse. This element has also been found to cause pneumoconiosis due to inhalation of dust containing cerium and associated with heart muscle disease. The growing industrial use of cerium and reports on cerium toxicity make it essential to have analytical procedures suitable for monitoring cerium in the environment. Electrochemical methods such as Adsorptive Stripping Voltammetry (AdSV) are often used to directly measure trace concentrations of metal ions in environmental samples. The AdSV technique is relatively easy, fast, and inexpensive. In this work, the optimization of measurement conditions ensuring reproducibility, high sensitivity and selectivity of the AdSV determination of Ce(III) in environmental waters was made. The determinations were carried out using glassy carbon as the working electrode and Alizarin as the complexing agent.
