The Cu(II) and Pb(II) loaded seashell powder spectra were established.
The spectral data obtained for the samples revealed broad absorption peaks at 1786, 1455, 1082, 855, and 709 cm?1
which are common characteristic features of the carbonate ions in calcium carbonate and are the fundamental modes of vibration for this molecule
The peak at 1077 cm?1 was only observed in the aragonite spectrum of calcium carbonate
As seen in Fig. 2, there are obvious differences between the peak intensity of Cu(II) and Pb(II) loaded seashell powders.
Peak intensity increased with increasing heavy metal biosorption on seashell powder
