Photocatalytic Degradation of Perfluorooctanoic Acid
2014Perfluorooctanoic acid (PFOA) is an emerging persistent organic pollutant receiving increasing attention due to its global occurrence and resistance to most conventional degradation methods. Some special techniques such as ultrasonication, aqueous electron reduction, persulfate photolysis, and phosphotungstic-acid photocatalysis have been developed to ...

Solar photocatalytic degradation of Aldrin
Catalysis Today, 2002Abstract Photocatalytic degradation of the pesticide Aldrin dissolved in water was carried out, in one case, using concentrated solar radiation and, in another case, using non-concentrated solar radiation. In these experiments, the effects of catalyst concentration, oxidant agent concentration, and solar irradiation were tested.

The Photocatalytic Degradation of Imazapyr
Monatshefte für Chemie - Chemical Monthly, 2007The degradation of imazapyr, an imidazolinone herbicide, in aqueous solution has been investigated with TiO2 slurry as photocatalyst at 30°C under UV radiation. The depletion of imazapyr concentration in an aqueous suspension followed 1st order kinetic behavior.

PHOTOLYTIC AND PHOTOCATALYTIC DEGRADATION OF PHARAMCEUTICALS
2016Pharmaceuticals are highly diverse group of compounds used for treating and preventing diseases in humans and animals. They are designed to be biologically active and therefore they might negatively affect non- target living organisms. Owing to the advances of different analytical methodologies during the last decade, the widespread occurrence of these

Photocatalytic degradation of E. coliform in water
Water Research, 2003This study aims to further investigate the total mineralization of the bacteria to the extent of death and cell-mass inactivation using a TiO2-Fe2O3 membrane photocatalytic oxidation reactor. Experimental results clearly indicated that dissolved oxygen (DO), hydraulic retention time (HRT) and concentration of the model bacteria (Escherichia coliform ...

Photocatalytic Degradation Of Dyes
Introduction Water pollution is an escalating global issue, with industrial effluents being one of the major contributors. Many synthetic dyes are known to be toxic, carcinogenic, and mutagenic. When released into aquatic ecosystems without adequate treatment, they can significantly reduce light penetration, disrupt photosynthetic activity in aquatic ...openaire +1 more source
Photocatalytic degradation of sulfa drugs
2012Pharmaceuticals are chemical substances which are used to treat and prevent disease in human and in animals. In farming they are also used as additives to feedstock in order to promote growth in animals. The presence of pharmaceuticals in the environment raises a big concern due to their continuous input in the environment via different pathways.

Photocatalytic degradation of pesticides
2013Pesticidi su postojani organski toksični spojevi, najčešće sintetskog podrijetla, koji su u većini slučajeva otporni na fotolitičku, biološku i kemijsku razgradnju. Smatra se da danas na svjetskom tržištu postoji oko 1500 aktivnih tvari s pesticidnim učinkom.
