Studies Of Enset (enset Ventricosum) For Major Minor And Trace Elements

This paper presents the concentration of K, Ca, Mg, Fe, Zn, Co, Cr, Pb, Cd, Cu, Ni, and Mn inrnEnset ventricosum. Samples of enset were collected from Wolliso (Oromiya region) andrnWolkite (SNNPRG) in March 2006. Total acid (4 mL mixture of HNO3 and HClO4) digestionrnmethod was employed and determination was made by flame atomic absorption spectrometry.rnThe percentage recoveries of the metals were in the range of 85% to 120%. The ranges of thernconcentrations (μg/g) of the metals on dry weight basis are: Ca 36,100 – 39,100; Mg 24,900 –rn26,900; K 14,100 – 32,200; Zn 11.9 – 42.3; Cu 1.5 – 5.2, Co 2.8 – 10.5; Cr 5.8 – 7.6; Fe 18.2rn– 54.4; Mn 2 _ 5; Ni 1 – 4 and Cd 0.6 _ 1.8.. The result obtained implies the plant is rich inrncalcium, magnesium and potassium and has small concentration of non-essential tracernelements.rnKey words: Enset, Enset ventricosum, Acid digestion, Major elements, Minor Elements,rnTrace Elements, Flame atomic absorption spectroscopyrn.
