“…Both sets of Qe values are somewhat in agreement with the experimental values, 39.92mg/g (MO) and 42.87 mg/g (AMX), however, the pseudo first order values are closer. Pseudo firs order kinetics describes a physiosorptive processes involving non-bonding forces (Chitongo et al, 2019). This may have also contributed to the adsorption process for both MO and AMX, as shown…”

In this study, we determined the capacity of metal organic framework, which we prepared by the solvothermal mixing of Zn ions and 1,4-benzenedicarboxylic acid (Zn/BDC) moieties to adsorb methyl orange (MO), and amoxicillin (AMX). Results obtained show that MO and AMX adsorption capacity by Zn/BDC (mg/g) was found to increase with increase in solution concentration, for each contaminant type. Three isotherm models were applied to the adsorption data: Freundlich, Langmuir, and Temkin. R2 values obtained for the adsorption of MO, 0.9778, 0.8589 and 0.9038 for Freundlich, Langmuir and Temkin plots respectively, indicates that all three models fit the adsorption data appreciably good, with the Freundlich isotherm providing the best fit. Those for AMX, 0.6737, 0.0616, and 0.5300 indicated a poor fit, but the Freundlich isotherm came out as best fitting isotherm for AMX, an indication of a multilayer adsorption process. Maximum possible amount of contaminant adsorbed per gram of Zn/BDC deduced from the Langmuir isotherm for the adsorption of both contaminants were 93.46 mg/g and 18.41 mg/g for MO and AMX respectively. This, among other indicators, showed the preference of Zn/BDC for MO relative to AMX. Adsorption kinetic models: pseudo first order, pseudo second order, and Weber-Morris intraparticle diffusion models, gave R2 values that indicate that intraparticle diffusion dominated the adsorption of MO, while the adsorption of AMX followed pseudo second order kinetics, an indicator of chemisorptive mechanism. Calculated Qe values, were in close agreement with experimental values.

“…In addition, the adsorption of ampicillin was declined at pH values higher than 7. The formation of electrostatic repulsion forces between carboxylate groups present in ampicillin molecules and the negative surface charges of the ACAF could describe the observed event in these pH values [ 39 ]. Moreover, it is expected that π-π interaction between a benzene ring of ampicillin and ACAF happens, which leads to the developing of adsorption capacity [ 40 ].…”

In this study, the effectiveness of activated carbon prepared from the Azolla filiculoides fern (ACAF) in order to remove ampicillin from aqueous solution was examined. The preparation of the ACAF was performed through chemical and physical activation processes with the presence of ZnCl 2 and at a temperature of 450 °C. The ACAF yield was 44.7% of the fresh Azolla filiculoides . The results obtained from the characterization study indicate that the prepared ACAF has excellent surface and internal properties to be used as an adsorbent. The surface area, porosity, and pore volume were estimated to be 716.4 m 2 /g, 51.2%, and 0.621 cm 3 /g, respectively. The functional groups in ACAF that were responsible for the adsorption of ampicillin molecules were detected using FTIR analyses. The maximum efficiency (96.84%) and uptake (114.3 mg/g) of ACAF to remove ampicillin were achieved under the following conditions: ACAF dose = 0.8 g/L, pH = 7, concentration of ampicillin = 100 mg/L, contact time = 60 min, and temperature = 45 °C. It was found that the kinetic and isotherm data matched the pseudo-second-order and Langmuir models with high precision values, respectively. Considering the thermodynamics of the adsorption, the endothermic and spontaneous nature of the ampicillin adsorption onto ACAF was approved. The ampicillin adsorption capacity by ACAF was not significantly affected by the presence of different concentrations of NaNO 3 competitor ion. The considerably higher adsorption capacity of the ACAF for ampicillin (114.3 mg/g) than other previously used adsorbents with excellent regeneration level (five cycles) depicts the superior performance of ACAF in the adsorption systems.

“…Thermodynamic analyses also revealed that the sorption of CHLR was an exothermic reaction that was conceivable but not spontaneous as the temperature rose. 104 The adsorptive removal of antibiotic contaminants from wastewater using biochar from peanut shells was studied. 105 In this study, chloramphenicol served as the reference antibiotic.…”
