In the recent years, pollution of the environment by heavy
metals has received considerable attention. Nickel is a moderate toxic element
compared to other transition metals.
However, it is known that inhalation of nickel and its
compounds can lead to serious problems, including respiratory system cancer.
Moreover, nickel can cause a disorder known as nickel-eczema. Nickel
is an excellent alloying metal in steel industry and is the metal component
of the enzyme urease and as such is considered to be essential to plants and
some domestic animals.
This metal normally occurs at very low level in the
environment, so sensitive methods are needed to detect it in most environmental
samples. Thus, the development of simple methods for selective determination of
nickel in trace amounts in different matrices is critical.
