Content estimation of the mineral elements (Zn, Mg, Cu, Fe, Co and Ni) in parsley at Aleppo region Syria by flame atomic absorption spectroscopy

Metals estimation Zn, Mg, Cu, Fe, Co and Ni in parsley grown in Syrian Aleppo City in three different areas (AlsheikhSaeed, Alwadihi, and Alramouseh) were determined by flame atomic absorption spectrometry (FAAS). The experiments were carried out using atomic absorption spectrometry after wet and microwave digestion methods, in Nitric Acid as digesting solution. The concentrations of the analyzed dried parsley samples in two digestion methods were similar for each metal, we noticed that the relative standard deviations (RSD%) was higher by wet digestion method while the value did not exceed 4.27% in microwave digestion method. The use of microwave digestion system provides a better digestion, with a short period, not exceeding ten minutes in closed containers, where the microwave digestion is not associated with contamination of the sample or laboratory.
