Nigeria. *Corresponding Author E-mail: Abstract: The need to clean-up heavy metal contaminated environment can not be over emphasized. This paper describes the Adsorption isotherm studies of Cd (II), Pb (II) and Zn (II) ions from aqueous solution using unmodified and EDTA-modified maize cob. Maize cob was found to be an excellent adsorbent for the removal of these metal ions.
ture of 30 0C and pH of 7.5, 2 grams of the cob was put into 100ml of the metal ion solution of known concentration. At the end of the …
