AB  - The goal of this research is to investigate the effect of SrO and La2O3 addition on the crystallization characteristics and sintering behavior of polyphosphate glasses. Differential scanning calorimetry (DSC), hot stage microscopy (HSM), X-ray diffraction (XRD), and scanning electron microscopy (SEM) methods were used to investigate the crystallization and sintering behaviors of glasses. The addition of SrO and La2O3 (1 or 5%), at the expense of phosphate mole fraction in polyphosphate bioactive glass, raises the characteristic temperature of glasses, and resistance to crystallization. Furthermore, the temperature of maximal shrinkage increases with the addition of SrO and La2O3. Surface crystallization is the dominant mechanism of crystallization in all samples. All glasses show complex crystallization leading to the formation of several crystalline phases. Sintered phosphate glass-ceramic containing bioactive beta-CaP2O6, alpha-Ca-3(PO4)(2,) and beta-Ca-3(PO4)(2) phases were successfully prepared.

AB  - Zeolites are inorganic, crystalline aluminosilicates that nowadays has been used as
adsorbents, catalysts and carriers of catalytically activated substances, due to the small size
of their pores, large internal surface, and well-defined chemical composition. In this paper,
the modification of beta zeolite using (3-aminopropyl)-triethoxysilane (APTES) was
investigated. The results of the Fourier transform infrared spectroscopy and
thermogravimetric analysis confirmed the presence of amino groups derived from APTES
onto the modified zeolite surface. APTES-enriched zeolite was further used as an adsorbent
of silver ions from aqueous solutions. The obtained results reveal that a zeolite after
modification exhibited significantly better adsorption efficiency (97%) in comparison to the
unmodified (37%). The kinetic data follows the pseudo-second-order model which
indicates a chemical interaction between silver ions and functional amino groups on the
surface of the silanizedbeta zeolite. Ag-APTES enriched beta zeolite also was studied as
anantibacterial agent toward the pathogenic bacteria Gram-negative Escherichia coliDSM
498 and Gram-positive Staphylococcus aureus ATCC 25923.

AB  - By-products from zinc hydrometallurgy are classified as hazardous waste with strong leaching toxicities. Even though numerous research papers are dedicated to valorizing valuable metals in it, the primary management route is still disposal or partial reuse, such as the Waelz process. Presented experimental research investigates possibilities of sulfidization and further processing as a technologically sustainable route for valuable metals valorization from non-standard jarosite-PbAg sludge. The comprehensive thermodynamic analysis was done by HSC Chemistry(R), through optimizing process parameters, i.e., temperature, sulfur addition, and selection of possible additives. Technological possibility of magnetic separation, flotation, and smelting of sulfidized material was also investigated; the results were below the values that allow practical application, due to the obtained texture of sulfidized jarosite, which does not allow the liberation of minerals. Smelting tests were performed on sulfidized jarosite with sulfur and without and with carbon as additive. By smelting sulfidized jarosite-PbAg sludge with added carbon in sulfidization stage at 1375 degrees C, obtained products were matte, slag, raw lead, and dust in which base, critical, and slag forming components were valorized. Valuable metals were concentrated in smelting products so as to enable further processing, which also could be interesting in the case of treatment of complex, polymetallic, and refractory primary materials, which represent a significant contribution to the circular economy.
