چکیده
Advanced oxidation processes, such as using titanium dioxide (TiO2) photocatalysis, are being developed to reduce or eliminate the toxicity of treated water. In this study, removal purified anatoxin-a (ANTX-a), live Dolichospermum flos-aquae cells, and a cell extract organism under UV-A/TiO2 creation decomposition products their were investigated. Total degradation ANTX-a from initial concentration 10 mg·L−1 with addition TiO2 UV-A irradiation was achieved in 30 min. Under these conditions several noted m/z ratio 156.11 216.1. Analysis completely degraded sample Thamnotoxkit F™ test showed that it no longer toxic. photocatalysis also efficient living cyanobacterial cells. Degradation structures released toxin Earlier homogenization cyanobacteria culture significantly accelerated

متن کاملTitanium 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...
