  • Calcium carbonate-carboxymethyl chitosan hybrid materials 
    Fortună, Maria-Emiliana; Ungureanu, Elena; Jităreanu, Carmenica-Doina (MDPI, 2021-06-16)
    In the present work, precipitated calcium carbonate (PCC) and carboxymethyl chitosan (CMC) were prepared to obtain new hybrid materials used in papermaking. In the first step, oc‐ curred the precipitation of CaCO3 in ...
  • Studies on kinetics and adsorption equilibrium of lead and zinc ions from aqueous solutions on Sarkanda grass lignin 
    Ungureanu, Elena; Trofin, Alina-Elena; Trincă, Lucia-Carmen; Ariton, Adina-Mirela; Ungureanu, Ovidiu C.; Fortună, Maria-Emiliana; Jităreanu, Carmenica-Doina; Popa, Valentin I. (Editura Academiei Romane, 2021-06)
    In this study, the adsorption of Pb2+ and Zn2+ ions from aqueous solutions onto lignin obtained from unmodified Sarkanda grass was analyzed. To ensure optimal process conditions, the retention of lead and zinc ions was ...
