Dangerous bisphenols and pesticides can be removed from water using nanosorbents from UJEP.

Researchers from UJEP, in cooperation with the Institute of Inorganic Chemistry of the Czech Academy of Sciences, are preparing powdered nanosorbents based on cerium and bismuth oxides, which can remove not only pesticides from water, but also substances that can disrupt the hormonal system of animals and humans (so-called bisphenols). Once bound to the surface of the sorbent, these toxic substances can also be effectively decomposed with the assistance of light. For the practical use of nanomaterials in new technologies, it is also necessary to study how they can influence biota and the environment. Therefore, the prepared nanosorbents were subjected to a series of toxicity tests for cells of mammals and aquatic organisms, including bacteria, algae, invertebrates or fish. The results of these tests indicate that the prepared nanomaterials have very low toxicity and are therefore promising for use in modern cleaning technologies.
