Assessment of three digestion procedures for Zn contents in Pakistani soil by flame atomic absorption spectrometry
چکیده انگلیسی

Evaluation of three different digestion procedures for accurate determination of elemental concentration in soils was undertaken. The digestion procedures, two leaching and a total dissolution processes were compared for twenty-one soil samples. The soil standard reference materials (SRMs), IAEA Soil-5 and IAEA Soil-7 were analysed for quality control purposes. Zinc (Zn) was analysed using flame atomic absorption spectrometry (FAAS). Precise analysis was accomplished in the SRM and soil samples, which was better than 4.7% for leaching and total dissolution procedure. Compared with the elemental concentration in soil samples, HF–HClO4 procedure achieved greater accuracy, where as HNO3–H2O2 and HNO3–H2SO4–HCl procedures were comparable with slight variation in a few samples.
