  • Adsorption of direct green 6 dye onto modified power plant ASH 
    Harja, Maria; Kotova, Olga; Samuil, Costel; Ciocinta, Ramona-Carla; Ciobanu, Gabriela (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2017)
    Power plant ash and modified ash were used as the adsorbent, in this study, for the removal of textiledye direct green 6 (DG6) from aqueous solutions. The adsorbent was prepared by the alkaline attack in aqueous medium ...
  • Adsorption performance of modified fly ash for copper ion removal from aqueous solution 
    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 ...
  • Asymmetric cellulose acetate membranes used in separation applications 
    Ciobanu, Gabriela; Favier, Lidia; Harja, Maria ("Ion Ionescu de la Brad" University of Agricultural Sciences and Veterinary Medicine, Iași, 2021-03-31)
    This work focused on the use of cellulose acetate polymer for the preparation of porous asymmetric membranes using a phase inversion process. These membranes were characterised by scanning electron microscopy, a bubble-point ...
  • 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 ...
