Molecular spectroscopic investigation of Ismaillia canal sediment (Egypt)

Abstract

This work has been conducted to study the molecular strcuture of sediments from 12 selected locations along Ismaillai canal. FTIR spectruma were assigned which indicating the possible interaction between heavy metals and humic acids. This is clear through the shift in the COOH band into COO asymmetric stretching of metal carboxylate around 1632 ~ 1637 cm-1. Another insight into the molecular structure of sediment is shown as the spectra are deconvoluted. Deconvolution indicates the existence of no reacted humic acid which confirms the process of metal interaction with organic acids reflected in the spectra.
