Determination of Manganese in Cassava Leaves by Slurry Sampling Flame Atomic Absorption Spectrometry

摘要: Abstract Cassava, Manihot esculenta crantz, constitutes one of the main foods consumed by most population developing countries, mainly in low income. It is largely used for its cost and diversity root leaves products. In this paper, a slurry sampling flame atomic absorption spectrometric method determination manganese cassava proposed. The was order to shorten analysis time minimize problems associated with solid sample treatment such as wet acid digestion, dry-ashing, contamination, analyte loss. samples were washed extran 10% (v/v), soon afterwards they dried an oven 60°C, triturated mill spheres, obtained material sifted mesh 100 micrometers. Then 0.1 g weighed balloons volumetric flask, volume completed 25 mL nitric 2,0 mol L−1, followed 20 minutes ultrasonic ba...
