    Buema, Gabriela; Harja, Maria; Lupu, Nicoleta; Chiriac, Horia; Forminte, Loredana; Ciobanu, Gabriela; Bucur, Daniel; Bucur, Roxana-Dana (MDPI, 2021-01-16)
    The initial characteristics of Romanian fly ash from the CET II Holboca power plant show the feasibility of its application for the production of a new material with applicability in environmental decontamination. The ...
  • Fly ash magnetic adsorbent for cadmium ion removal from an aqueous solution 
    Buema, Gabriela; Lupu, Nicoleta; Chiriac, Horia; Herea, Dumitru-Daniel; Favier, Lidia; Ciobanu, Gabriela; Forminte, Loredana; Harja, Maria ("Ion Ionescu de la Brad" University of Agricultural Sciences and Veterinary Medicine, Iași, 2021-03-31)
    The fly ash generated from a Romanian power plant was used as a starting material in this study. The aim of the study was to obtain a low cost material based on the treatment of fly ash with Fe3O4 for utilization as ...
  • Performance assessment of five adsorbents based on fly ash for removal of cadmium ions 
    Buema, Gabriela; Lupu, Nicoleta; Chiriac, Horia; Ciobanu, Gabriela; Bucur, Roxana-Dana; Bucur, Daniel; Favier, Lidia; Harja, Maria (Elsevier B.V., 2021-03-18)
    Five adsorbents based on fly ash treated with NaOH for the adsorption of cadmium ion from aqueous solutions were investigated. The materials were characterized using scanning electron microscopy (SEM), Fourier trans form ...
  • Recent advances in removal of Congo Red dye by adsorption using an industrial waste 
    Harja, Maria; Buema, Gabriela; Bucur, Daniel (Springer Nature, 2022-04-12)
    The Congo Red dye was removed from a simulated textile wastewater solution using fly ash from a local power plant. The characterisation of fly ash was studied in detail by SEM, EDX, XRD, FTIR, BET surface area and TGA ...
