Water contamination becomes a problem, which may limit civilization progress.
The development of a universal and inexpensive method of water purification is very difficult, because it may contain pollutants of different nature, e.g. heavy metals, organic compounds (pesticides, chlorinated aromatic compounds, antibiotics and surfactants) as well as bacteria. The water purification methods currently in use are based on osmosis, ion-exchange, adsorption, ultrafiltration, distillation and photooxidation. Although multifarious, they have limitations, mainly connected with their high power consumption and low efficiency.
Description of the technology
The subject of the offer covers hybrid photocatalysts based on nanoclays and their application to photocatalytic reactions, in particular in environment-friendly method of water purification. Offered material is based on natural, environmentally friendly minerals (e.g. kaolinite, bentonite, mica). The invention may purify water in a physical absorption process as well as in a photodegradation process, therefore offered materials combine the advantages of the photochemical and the adsorption method of water purification.
Specifications
The offered method of water purification is based on the photocatalytic degradation of contaminations. Photocatalysts are produced by modification of layered nanoclays with polymers that can absorb both visible and ultraviolet light. Experimental tests have shown that hybrid photocatalysts may efficiently degrade water pollutants as a result of oxidation by singlet oxygen, energy or electron transfer. Moreover, it has been proved that hybrid photocatalysts have the ability to adsorb hydrophobic compounds thereby additionally improving the water purification process. Hybrid photocatalysts are especially well-suited for the photodegradation of pesticides, aromatic compounds (e.g. chlorinated aromatic compounds), phenols and cyanides.
