Analysis of Heavy Metal Levels in Some Edible Fruits from Selected Markets in Ethiopia
Abstract: This study was conducted to determine the concentration of nine heavy metals (Zn, Fe, Cu,Mn, Co, Ni, Cr, Pb and Cd) in selected edible fruits namely: avocado, mango, papaya,pineapple, orange and banana purchased from Awassa and Addis Ababa markets. Dry ashing method was used for the digestion of samples. The heavy metals were analyzed using atomic absorption spectrophotometer (AAS). The results obtained showed that the concentrations of heavy metals in …

Preliminary Study on the Production of Activated Carbon from Moringa Oleifera Seed Shells by Thermal Activation Method
Abstract: Activated carbon was prepared from Moringa oleifera seed shells by thermal activation method. The carbonization and activation temperatures were 500, 600 and 700°C respectively, at 13 min for each process after pre-carbonization for 25 min. The pH of the activated carbon produced were 9.55 at 500°C, 9.78 at 600°C and 9.97 at 700°C while the yield decreased with increase in temperature as follows: 30.40% at 500°C, 29.35% at 600°C and …
