Interference by transition metals

Negative interferences by transition metal cations such as nickel and copper and nitrite were observed. However, these interferences have also been reported for the hydride generation atomic absorption method, and are due to... [Pg.236]

Bismuth can also be determined with excellent sensitivity using HG AAS the LOD of 0.03 igL is more than an order of magnitude better than with GF AAS. Various interferences by transition metals have been described which may be significant, especially for the analysis of metallurgical samples. Measures recommended to eliminate these interferences include the addition of potassium iodide, 8-hydroxyquinoline, thiosemicarbazide, or EDTA, performing the determination at higher acid concentra-... [Pg.673]
