“…[18,19] Subsequently, the simplified DO model was adopted for isotherm equations in mathematical simulation, successful predicting water vapor adsorption on porous carbons. [20,21] The initial quantitative adsorption isotherm models for water by Dubinin et al [22] were further refined by Stoeckli et al [23] using the Dubinin-Astakhov equation, adept at describing type IV and V isotherms, albeit without elucidating the specific adsorption mechanisms of water vapor. The DO model, proposed by DO et al, [24] based on the formation of water clusters with surface functional groups and final entering in the micropore, can comprehensively describe different shapes of water vapor adsorption isotherm and elucidates the adsorption mechanism on activated carbon.…”

In order to investigate the dynamic process of the heat and mass transfer phenomenon of water vapor on activated carbon, a fixed‐column adsorption unit and two kinds of activated carbon were used as adsorbent for water vapor adsorption under the adsorption temperature 293.15 K, 303.15 K and 313.15 K, respectively. A coupled model was developed by mass and energy balance, mass transfer and simplified DO adsorption equilibrium equation. The effects of physical parameters on heat and mass transfer were theoretically investigated. Results show that the numerical model match well with the experimental data (R2>0.993). The axial diffusion coefficient (DL) increases from 1.226×10−6 m2 s−1 to 4.062×10−6 m2 s−1 for RAC and 1.425×10−6 m2 s−1 to 4.030×10−6 m2 s−1 for MAC, mass transfer coefficient (k) increases from 8.171 s−1 to 27.083 s−1 for RAC and 9.499 s−1 to 26.864 s−1 for MAC. Concurrently, the breakthrough time of adsorption water vapor gradually shorten from 1000 s to 780 s with temperature increasing from 293.15 K to 313.15 K. The effect of axial diffusion coefficient (DL) on mass transfer is not obvious. Furthermore, the influence of the mass transfer coefficient (k) on temperature variation rate surpasses that of the internal heat transfer coefficient (h).

In this study, the MgFeCa layered double hydroxides was supported in biochar (B) using coprecipitation, hydrothermal, and co-pyrolysis methods. The prepared B-MgFeCa composites were investigated for tetracycline (TC) adsorption from an aqueous solution. The B-MgFeCa composites synthesized through co-precipitation and hydrothermal methods exhibited better crystallinity, functional groups, and well-developed LDH structure within the biochar matrix.However, the co-pyrolysis method resulted in the LDH structure breakage, leading to the low crystalline composite material. The maximum adsorption of TC onto all B-MgFeCa was obtained at an acidic pH range (4-5). The B-MgFeCa composites produced via hydrothermal and copyrolysis methods showed higher and faster TC adsorption than the co-precipitation method. The kinetic results can be better described by Langmuir kinetic and mixed order models at low and high TC concentrations, indicating that the rate-limiting step is mainly associated with active binding sites adsorption. The Sip and Freundlich models showed better fitting with the equilibrium data. The TC removal by B-MgFeCa composites prepared via hydrothermal and co-pyrolysis was mainly dominated by physical and chemical interactions. The composite obtained via the coprecipitation method adsorbed TC through chemical bonding between surface functional groups with anionic species of TC molecule. The B-MgFeCa composite showed excellent reusability performance for upto five cycles with only 30% decrease in TC removal efficiency. The results demonstrated that B-MgFeCa composites could be used as promsing sorbent material for effective wastewater treatment.
