Comparison of Digestion Methods Using Atomic Absorption Spectrometry for the Determination of Metal Levels in Plants

Trace metal elements (TMEs) are among the most important types of pollutants in environment. Therefore, a precise determination these contaminants several environmental components is required for safety assurance living organisms. Spectroscopic analysis an efficient technique employed to detect and determine TME contents numerous samples. Hence, achieve reliable accurate results when using spectroscopic analysis, samples should be carefully prepared. In present study, comparison eight digestion methods five vegetal was carried out quantify Cd, Mn, Al Mg atomic absorption spectroscopy technique. According extraction techniques used this showed outstanding difference levels determined same sample. The obtained indicated that highest Mn concentrations were recorded mixture HNO3-HClO4 studied species: atriplex portulacoides, arthrocnemum indicum, olea europaea BCR-62, ulva lactuca BCR-279 compared all other methods. Regarding our heated different acids (HNO3-H2SO4-HClO4, HCl-HNO3, HNO3-HClO4, HNO3-H2SO4, HNO3-HCl-HClO4 HNO3-HCl-H2SO4) BCR-279. Similarly, acid (efficient Cd) portulacoides indicum. However, extraction, revealed effectiveness method depended on plant species studied. findings, efficiency quantification by AAS depends procedure, metallic ion species.
