With the development of science and technology, sensitive, rapid, reproducible, simple and accurate analytical methods are required for the determination of trace elements in geological, biological and environmental samples. The direct determination of extremely low concentration of trace element with modern atomic spectroscopic method, such as atomic absorption spectrometry is so difficult. On one hand, the limitations are associated not only with the insufficient sensitivity of these techniques but also with matrix interference.
