✦ Synopsis

Feedstuffs can be effectively dissolved by treatment with concentrated sulfuric acid and (30 %) hydrogen peroxide in approximately (30 \mathrm{~min}) for the rapid determination of elements at both the (1 %) level and the trace level by flame and electrothermal atomic absorption spectrometry, respectively, This paper reports a new determinative method for calcium ( (10 \mathrm{~g} \cdot \mathrm{kg}^{-1}) ) and copper ( (10 \mathrm{mg} \cdot \mathrm{kg}^{-1}) ) based on this procedure. The relative standard deviation of the results was typically ca. (5 %). 1995 Academic Press. Inc
