Differential infrared spectroscopy was used to investigate parathion degradation in the adsorbed state. This technique enables observations of the 1,380–1,150 cm−1 region, which is usually overlapping with the strong SiO absorption of bentonites. The appearance of the P=O absorption band upon heating clay-parathion complexes, in conjunction with other tests, confirmed that parathion degradation on bentonites occurs mainly via a rearrangement reaction.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
