Floating photocatalyst for water organic contaminants removal
keywords: photocatalyst, photodegradation, titanium dioxide, water pollution, antibiotics
offer number: 409

Offered hybrid photocatalysts is based on the thermally expandable polymer microspheres coated by a TiO2 layer. The catalyst has a controllable buoyancy (density).

 

Organic contaminants in water and waste water

The contamination of drinking water by a organic substances coming from industry, pharmaceutical or pesticide residues becomes more common.

Often, the source of harmful substances is the municipal sewage, where the pharmaceuticals residues and their metabolites are expelled and then cumulated. As the sewage system commonly does not separate it, the surface water often becomes a final collector of many organic contaminants. More, because of the exploitation of this water, the contaminants are spread to other ecosystems.

The pathways of veterinary medicinal product residues or the residues of pesticides widely used in agriculture, which are biologically active, are even shorter.

What is important, these substances negative impact on human health, like chronic toxity effect, endocrine disorders or drug resistance is noticable with very low concentrations.

Therefore, there is a great need to the technologies enabling to treat and depurate the surface water as well as drinking water.

 

Synthesis method and the advantages

The catalytic systems basing on TiO2 in the form of slurry that have been used so far, have many limitations, like very low sedimentation velocity of TiO2 aggregates. Moreover, the slurry is turbid and consequently the depth of light penetration is small. On the other hand, comparing to photocatalyst suspension systems, the photocatalytic activity of titania in the supported form is typically lower.

Because of the high incompatibility of inorganic crystalline compound such as TiO2 and organic amorphous polymer forming the microspheres, such systems were not widely used so far.

The photocatalysts developed on Jagiellonian University is received on the way of hydrolysis under mild conditions. The deposition of TiO2 on the surface of the microspheres is confirmed in SEM images. Thanks to the floating of photocatalysts particles, the access of light is assured and the surface area is maximized, while the removal and reuse of the material is facilitated.

 

Operating effects

So far, using the floating TiO2 photocatalysts, the photodegradation of: cephalothin, amoxycilin, sulfamethoxazole as well as ibuprofen and phenol (as the representative compound of wastewater contaminants) was studied and confirmed.

 

The technology was applied for a patent protection to Polish Patent Office on June, 19th, 2018.

JU scientists to develop biological agricultural support solutions
The project “Interactions between plants and microorganisms in response to the presence of potentially toxic metals, metalloids and silicon (Si)” by Prof. Katarzyna Turnau from the JU Faculty of Biology won a grant from the Polish National Agency for Academic Exchange. The study aimed at replacing the widespread use of agrochemicals with biological agricultural support solutions will also involve researchers from Slovakia and Austria.
JU students will help people suffering from depression
Therapify is a mobile application designed to help depressed people. It was first conceived by Łukasz Pstrong, a graduate of the AGH University of Science and Technology in Kraków, and developed over the course of the last two years with collaborators from his university, the Jagiellonian University, and SWPS University of Social Sciences and Humanities in Warsaw.
Plakaty Demo Day II +
In January, we complete the project managed by CTT CITTRU as part of the program of the Ministry of Science and Higher Education - Incubator of Innovation +. We supported, among others, 18 research teams selected in the competition, that develop innovative technologies. Thanks to the funds granted by CTT CITTRU and hard work of technology transfer officers, pre-implementation research was financed, which increased the attractiveness of these inventions and investors interest in them. Take look at the gallery of posters for technologies, developed as part of the project. What do you think about it
