AmanMangalmurti Kara Newman Leong Qi Dong Soh Han Wei Maximization of ethanol yield and adsorption of heavy metal ions by fruit peels
Hypothesis • Ethanol yield from fermentation differs for both peels • The efficiency of heavy metal ion adsorption differs for both peels • The order of adsorption and fermentation has an effect on the ethanol yield and the efficiency of adsorption
Apparatus & Materials Apparatus Materials Zymomonasmobilis Glucose-yeast medium Sodium alginate medium Calcium chloride solution Sodium Chloride solution Fruit peel Deionised water Dinitrosalicylicacid Acidified potassium chromate solution Lead (II), Copper (II), Zinc (II) ion solutions Lead (II), Copper (II), Zinc (II) reagent kits • Centrifuge • Centrifuge tube • Spectrophotometer • Spectrophotometer cuvettes • Glass rod • Dropper • Sieve • Blender • Boiling water bath • Shaking incubator • Fractional distillatory • Quincy Lab Model 30 GC hot-air oven • Rotary Mill • Sieve: 0.25mm (60 Mesh)
Methods Ethanol fermentation Adsorption of heavy metal ions
Ethanol Fermentation Preparation of Z. mobilis, Extraction of Sugars, Fermentation, Determination of Yield
Adsorption of heavy metal ions Pre-treatment of peel, Creation of heavy metal mixture, Adsorption, Determination of final ion concentration
