    REMOVAL OFHEAVY METALS FROM RIVER WATER USING ACTIVATED CARBON OF EUCALYPTUS GLABULUS BARK (BAHIRZAF)
    (HAWASSA UNIVERSITY, 2024-10) YIDAGNU FEREDE
    Heavy metal pollution has become one of the most serious environmental problems nowadays. The removal of heavy metals from the environment is of special concern due to their persistence. Batch experiments were conducted to test the ability of activated carbon for the removal of lead, nickel, copper and zinc from water Heavy metal pollution in the marine system has become a seriousthreattodayandofgreatenvironmentalconcernastheyarenon-biodegradableandthuspersistent. Eucalyptus glabulus bark locally named as ‘Bahirzaf’ collected aleta wendo town from area around were used for activated carbon preparation. Dumps and polluted water Activated carbon wasprepared synthesized from bio-waste materials of the plant Eucalyptus barks. This work deals with the preparation of activated carbon from Eucalyptus leave store move heavy metal ions: such as Cu(II),Pb(II),Zn (II),and Ni(II)from aqueous solution. Chemical activation of the carbon was done by H3PO4, H2SO4, KOH and Characterization includes pH. The optimum temperature used to prepare activated carbon of Eucalyptus leaves was 500 oC while the optimum pH value and contact time for activated carbon of Eucalyptus leaves was determined as6and60minrespectively.Theoptimumenvironmentsforadsorbentsdosewasdetermined0.041 g in 25 ml solution. Thermodynamic analysis asserted endothermic and spontaneous nature of the system with involvement of chemical adsorption process. Equilibrium data were represented better by the Freundlich model than the Langmuir model which describes a multilayer adsorption.
