文摘

A strategy for selective determination of Cr (VI) was developed. The method was based on a FI-SPE-FAAS system. An anion exchanger was used as solid sorbent. An improvement treatment of the analytical signal is reported. The limit of detection was two order lower than that expected quantifying by FAAS.
