摘要	It was observed that the atomic fluorescence emission due to As(V) could has a 10% to 40% of fluorescence emission signal during the determination of As(Ill) in the mixture of As(Ill) and As(V). Besides, interferes from heavy metals such as Pb(II), Cu(II) can cause severe increase of the signals as compared to the insignificant effects caused by Cd(II), Zn(II), Mn(II) and Fe(III). On the basis of further studies, the masking agent of 8-hydroxyquinoline was used as an efficient agent to eliminate interference of As(V) emission and the heavy metal of Cu2+ and Ph2+ in the measurements of arsenic species. After a series standard additions and CRM researches, a sensitive and interference-free analytical procedure was developed for the speciation of arsenic in samples of porewaters and sediments in Poyang Lake, China.
