Abstract
A flow injection analysis coupled to atomic spectroscopy was developed to determine Ca, Mg, Mn, K, Na and Zn in honey. The following paramet ers were established: 30 cm dispersion tube length, 6 ml/min carrier s olution flow-rate and 430 mul sample volumen. Matrix influence was not observed in any mineral element. Detection limits (in mug/g) were: Ca , 1.6; Mg, 4.8; Mn, 0.8; K, 27.0; Na, 3.6 and Zn, 0.4. Precision value s (in %) were: Ca, 4.3; Mg, 7.4; Mn, 7.2; K, 1.4; Na, 2.7 and Zn, 9.8; and recovery percentages values were: Ca, 92 +/- 3; Mg, 125 +/- 7; Mn , 98 +/- 9; K, 65 +/- 3 Na, 101 +/- 4 y Zn, 99 +/- 41. This method was applied to determine those minerals in honey samples from different f loral origins.
