Malathion is one of the most commonly used
organophosphorous pesticides worldwide. Gold nanoparticles
can be used for the degradation and removal of
10 ppm malathion. The morphology of the prepared gold
nanoparticle is characterized by transmission electron microscopy.
Photodegradation of malathion on irradiation to
different light sources was monitored using different tools
such as UV–visible spectra and high-performance liquid
chromatography. Photodegradation rate of malathion was
enhanced in the presence of gold nanoparticles as a result
of surface plasmon phenomena.
