    Biosorption of Cr(VI) from AqueousSolution Using New Adsorbent: Equilibrium and Thermodynamic Study by Israa G. Zainal

    Published 2010-01-01
    “…The biosorption data was well fitted to Dubinin - Radushkevich (D-R), Freundlich and Tempkin adsorption isotherm models, although the correlation coefficient of Langmuir model was high but the calculated adsorption capacity did not agree with the experimental. The thermodynamic study reveals that the biosorption process is spontaneous and the spontaneity decreased with temperature increase and the process is exothermic accompanied by highly ordered adsorbate at the solid liquid interface. …”

    Adsorption Thermodynamics, Modeling, and Kinetics Studies for the Removal of Lead Ions Using ZnO Nanorods by Sadia Ata, Anila Tabassum, Ifra Shaheed, Ijaz ul Mohsin, Norah Alwadai, Maryam Al Huwayz, Munawar Iqbal, Arif Nazir

    Published 2023-01-01
    “…The elimination of lead ions was achieved at pH 6-7 using a 0.06 g adsorbent dose, 25 min contact time, 25 mg/L initial lead ion concentration, 323 K temperature, and 200 rpm agitation speed. A thermodynamic study revealed the endothermic nature of lead ion sequestration onto ZnO-NR. …”

    The Thermodynamic Relationship between the RN-AdS Black Holes and the RN Black Hole in Canonical Ensemble by Yu-Bo Ma, Li-Chun Zhang, Jian Liu, Ren Zhao, Shuo Cao

    Published 2017-01-01
    “…In this paper, by analyzing the thermodynamic properties of charged AdS black hole and asymptotically flat space-time charged black hole in the vicinity of the critical point, we establish the correspondence between the thermodynamic parameters of asymptotically flat space-time and nonasymptotically flat space-time, based on the equality of black hole horizon area in the two different types of space-time. …”

    Comparison of Aerosol Acidity Based on a Direct Measurement Method and a Chemical Thermodynamic Model by Qinping Song, Kazuo Osada

    Published 2023-09-01
    “…Abstract Aerosol acidity is an important parameter in aerosol science that affects many chemical reactions in the atmosphere, and it is often estimated using chemical thermodynamic models. The Extended Aerosol Inorganic Model IV (E-AIM IV) is frequently used for this purpose; however, due to the limited number of available direct measurement methods of aerosol acidity, there is still a certain degree of uncertainty with regard to how accurately the simulation results reflect reality. …”
