Therefore, it is essential to find solutions to the problems of water scarcity and water pollution. In this research, an experiment was designed to optimize the technique for the adsorption of Remazol Red F3B (RR) dye by lyophilized brewery yeast waste from the fermentation process. Moreover, we proved that brewery yeast is a great adsorbent. Batch adsorption experiments were carried out for optimization of different initial parameters, such as initial dye concentration (5–1000 mg/L), amount of yeast (0.5–2.5 g), pH (3–11) and temperature (20 to 40 °C). Furthermore, the structure and elemental composition of the adsorbent were analyzed with SEM, EDS and FTIR before and after biosorption. The best fits for the mathematical isotherm models in the case of the linear form were the Langmuir I and Freundlich models (R2 = 0.923 and R2 = 0.921) and, for the nonlinear form, the Khan model (R2 = 0.9996) was the best fit. The pseudo-second-order kinetic model showed the best fit for both linear (plotting t/qt vs. t) and nonlinear forms, are the calculated qe values were similar to the experimental data.}, year = {2022}, eissn = {1422-0067}, orcid-numbers = {Tonk, Szende/0000-0001-8833-7019; Rápó, Eszter/0000-0002-9028-6123} } @inproceedings{MTMT:32915442, title = {Adsorption of Remazol Brilliant Blue RR from Aqueous Solution with Calcined Ostrich Eggshells}, url = {https://m2.mtmt.hu/api/publication/32915442}, author = {Rápó, Eszter and Tonk, Szende}, booktitle = {Proceedings of the 7th World Congress on Civil, Structural, and Environmental Engineering}, doi = {10.11159/iceptp22.165}, unique-id = {32915442}, year = {2022}, pages = {165}, orcid-numbers = {Rápó, Eszter/0000-0002-9028-6123} } @article{MTMT:32601451, title = {Effectiveness and Characterization of Novel Mineral Clay in Cd2+ Adsorption Process: Linear and Non-Linear Isotherm Regression Analysis}, url = {https://m2.mtmt.hu/api/publication/32601451}, author = {Tonk, Szende and Aradi, László Előd and Kovács, Gábor and Turza, Alexandru and Rápó, Eszter}, doi = {10.3390/w14030279}, journal-iso = {WATER-SUI}, journal = {WATER}, volume = {14}, unique-id = {32601451}, year = {2022}, eissn = {2073-4441}, orcid-numbers = {Tonk, Szende/0000-0001-8833-7019; Aradi, László Előd/0000-0003-0276-3119; Kovács, Gábor/0000-0001-9622-5471; Rápó, Eszter/0000-0002-9028-6123} } @CONFERENCE{MTMT:32915727, title = {Ipari melléktermék lehetséges felhasználása a víztisztításban, reaktív festék adszorpciója}, url = {https://m2.mtmt.hu/api/publication/32915727}, author = {Rápó, Eszter and Tonk, Szende}, booktitle = {XXVII.
