Destruction of cyanobacterial toxins by semiconductor photocatalysis

Biodegradation of Cyanobacterial Toxins

Water is an essential natural resource, necessary for drinking, agriculture and industrial activities, and providing the human population with safe drinking water is one of the most important issues in public health. Cyanobacteria produce toxins that may present a hazard for drinking water safety. These toxins are structurally diverse and their effects range from liver damage, including liver c...

Cyanobacterial Toxins Impact Crops

Oregon surface waters are experiencing increased occurrence of potentially toxic cyanobacterial blooms (Fig. 1). It is necessary to use the modifier “potentially” because there is no toxin monitoring in the state of Oregon. Advisories are currently based on cell counts of potentially harmful cyanobacteria. This summary is intended to briefly review the recent research on the effects of a cyanob...

Destruction of Malodorous Compounds Using Heterogeneous Photocatalysis

Photocatalytic oxidation of the sulfur-containing compounds, trimethylene sulfide (C3H6S), propylene sulfide (C3H6S), thiophene (C4H4S), and methyl disulfide (C2H6S2), was carried out using an annular plug flow reactor with TiO2 in a supported form. Formation of products and byproducts was monitored in real time using a mass spectrometry online system. Mineralization of the sulfur-containing co...

Removal of Cyanobacterial Toxins by Strains of Probiotic Bacteria

Application of Semiconductor Photocatalysis for Effective Elimination of Organic Contaminants from Sewage

The ZnO/SiO2 semiconductor nanophotocatalysis was synthesized via sol-gel method. Also, theplatinum particles were loaded on the ZnO/SiO2 nanoparticles by photoreductive method. Thestructure of catalyst was confirmed by X-ray diffraction (XRD), scanning electron microscopy(SEM) andfourier transform infrared spectroscopy (FT-IR). The XRD patterns of ZnO particlesdisplayed the nanoparticles have ...
