Investigation of new materials for radioactive waste treatment and immobilization
- Supervisor: dr hab. Agnieszka Miśkiewicz, prof. ICHTJ
- Description: Proper management of radioactive waste generated in scientific research, in numerous applications of isotope techniques in industry and medicine, as well as in nuclear energy, is an important issue for the further development of nuclear techniques and nuclear power. Regardless of the source of their production, radioactive waste must be processed in such a way to ensure that their storage is safe for both humans and the natural environment.
  The PhD thesis aims to study the possibility of using new materials such as geopolymers or zeolites, based on raw materials and industrial wastes (fly ash, clay, etc.) for the treatment and immobilization of liquid and solid radioactive wastes. Among others, wastes containing organic species (e.g., liquid waste coming from the decontamination process, ashes from incineration process of organic RW) will be subjected to the treatment using these new materials. The research on the waste immobilization will focus on determining the impact of the waste composition on the consolidation process of the conditioning matrix, and its durability. A combination of new matrices with cement materials will be considered as well for immobilization of different types of radioactive wastes.

Degradation of sulfonamide antibiotics in aqueous solution under electron beam (EB) irradiation and EB coupled with conventional methods
- Supervisor: Dr. hab. Yongxia Sun, prof. INCT
- Description: We are seeking candidates for a PhD student position partially funded by III PL-CHN “TAPEB” project. The doctoral thesis will focus on the selected three sulfa antibiotics (sulfamethoxazole, sulfamethazine, and sulfadiazine) degradation in aqueous solution under EB irradiation . EB coupled with conventional methods (Fenton, O3) will be applied to study degradation of sulfamethoxazole as a representative compound. Several important factors (such as dose and water matrix etc.) influencing on the degradation efficiency of antibiotics will be studied; degradation intermediates of sulfa antibiotics will be identified. Computer modeling simulation will be performed to elaborate mechanism of degradation of selected sulfonamide antibiotics in water under EB irradiation.
