REMOVAL OF Zn(II) and Cu(II) IONS FROM AQUEOUS SOLUTION USING CHEMICALLY ACTIVATED CARBON DERIVED FROM PALMYRA SHELL

Abstract :

The ability of activated carbon prepared from palmyra shell (PAC) to remove Zn (II) and Cu (II) metal ions from synthetic effluent was investigated. The PAC was characterized using FTIR spectroscopy and SEM in order to ascertain the existence of functional groups and microspores responsible for adsorption of metal ions. The experiments were carried out in a batch system to optimize various experimental parameters like initial metal ion concentration, contact time, dose rate of adsorbent and pH. The adsorption data were well represented by Langmuir model. Kinetic studies showed that the adsorption rates were more accurately represented by a first order model. The obtained results confirmed the applicability of PAC as an efficient and economical adsorbent for the removal of heavy metal ions from waste water.
