| الوصف: | This paper describes the development of methods in micro-scale for the determination of K, Mg, Na and Zn in meat by atomic spectrometry techniques. The limits of detection (LOD) for K and Na by microdigestion were 0.18 and 0.20 mg g-1, respectively whereas LOD for Mg and Zn by microsolubilization with TMAH were 2.40 and 18.4 µg g-1, respectively. The RSD values were lower than 6.0% and the CRMs analyzed showed values with 95% agreement. The proposed methods are simple, fast and use small amounts of sample (around 10 mg) yet do not require special equipment for sample preparation. |
