Several techniques such as flame atomic absorption and voltammetric methods have been used for the determination of these ions in different samples. The cross-interferences among different metal species often cause problem using these methods, which in turn raise the uncertainty level in the analytical results. Further more, those techniques require expensive instrumentation and maintenance, which limit the application of the techniques in many laboratories.
