  • Chromatic kinetics in thermal field 
    Doncean, Gheorghe (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2014)
    The first section of the paper outlines the thermal kinetics of the thermoelectric cell and defines the thermistor as the heating element during the isothermal period. The paper then focuses on uniform wetting and heating ...
  • Kinetics of pumpkin dehydration 
    Șleagun, Galina; Cernîșev, S.; Popa, Maria; Fiodorov, S. ("Ion Ionescu de la Brad" University of Agricultural Sciences and Veterinary Medicine, Iași, 2007-02-23)
    The paper has studied the effect of drying temperature (50, 60, 70, 80, 90, 100ºC) and wind speed (1.3; 1.7; 3.3; 4.1 m/s) on the kinetics of dehydration in pumpkin. The experimental data were satisfactorily fitted to ...
  • Kinetics study of Pb(II) and Hg(II) removal from aqueous media on rapeseeds biomass 
    Arsenie, Teodora-Daniela; Bulgariu, Dumitru; Bulgariu, Laura (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iași, 2017)
    In this study, the removal of Pb(II) and Hg(II) ions from aqueous solution using rapeseeds biomass was examined in batch systemsas a funtion of contact time. The results obtained for the removal of each ...
  • 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 ...
  • Use of Sarkanda grass lignin as a possible adsorbent for as (III) from aqueous solutions – kinetic and equilibrium studies 
    Ungureanu, Elena; Jităreanu, Carmenica-Doina; Trofin, Alina-Elena; Fortună, Maria-Emiliana; Ungureanu, Ovidiu C.; Ariton, Adina-Mirela; Trincă, Lucia-Carmen; Brezuleanu, Stejărel; Popa, Valentin I. (Editura Academiei Romane, 2022-05-06)
    Considering the negative effects of polluting species on the environment and human health, in particular heavy metals, and the need for efficient use of resources, the present study investigated the adsorption of As (III) ...
