Heavy metals are group of metals and metalloids with atomic density that are five times more than water. The most toxic form of these heavy metals is when in the ionic species. In the environment, the heavy metals are generally more persistent than organic contaminants such as pesticide or petroleum by-products. The Fourier transform Infrared spectroscopy (FTIR) was used for the characterization of the plantain peel. The FTIR spectrum showed broad and intense absorption band obtained at a range of 3311 cm^-1 indicating the presence of intra- and inter-molecular hydroxyl groups. The bands at 2917 cm^-1 and 1375 cm^-1 showed the presence of aliphatic C-H stretching and bending vibrations respectively. The band at 1629 cm^-1 is indicative of an aromatic C=C stretching. The strong absorption band of C-O stretching vibration got disappeared from the spectra and these indicate that there was a difference between the two spectra used for the removal of these heavy metals from aqueous solution. Atomic Absorption Spectrometer (AAS) was used for the quantification of cobalt, copper and zinc and the highest removal was 97.7% (Co), 70% (Cu) and 60% (Zn) at pH 4 using 40 ppm.
