[en] The interference of iron in the determination of zirconium by atomic absorption spectrophotometry was studied. Attempts were made to emininate this interference by complexing the iron with EDTA, ascorbic acid and hydrazine; also by the addition of ammonium fluoride to the solution. Some experiments were carried out in order to explain the results obtained

Foi estudada a interferencia do ferro na determinacao do zirconio por espectrofotometria de absorcao atomica. Procurou-se eliminar esta interferencia, nao so complexando o ferro com EDTA, acido ascorbico e sulfato de hidrazina, como tambem pela adicao de fluoreto de amonia a solucao. Algumas experiencias foram realizadas no sentido de explicar os resultados obtidosJournal
