Titanium dioxide mediated photocatalytic degradation of malathion in aqueous phase

The photocatalytic degradation of technical grade pesticide ‘malathion’ has been studied in aqueous suspensions of TiO2. The main aim of using this process is to degrade the toxic complex structure of the pesticide to harmless products by treating the sample in the UV-reactor. The COD measurements are carried out in order to study the percentage mineralization and degradation is studied under d...
