摘要：

A procedure is described for the rapid determination of calcium, magnesium, iron and zinc in flours obtained from several grains and legumes (wheat, whole meal, maize, barley, rice, rye, vetch, soy bean and field bean) using flame atomic absorption spectrometry. Suspensions up to 3% m/V from the ground samples are directly introduced into the spectrometer using a simple flow injection manifold. Calibration is performed using aqueous standard solutions of the determinands. The results obtained with this procedure agree with those obtained by conventional dry-ashing followed by dissolution in acids. Results for two standard reference materials are also given.
