“…On the contrary, it is clear that the Langmuir-1 isotherm more closely reflects the experimental data when the single-layer adsorption capacity and correlation coefficients are calculated using the other four Langmuir model linear expressions [40]. This result demonstrates that adsorption occurs in a single layer and is homogeneous [53,54].…”

Antibiotics are among the most critical environmental pollutant drug groups. Adsorption is one of the methods used to eliminate these pollutants. In this study, activated carbon was produced from pumpkin seed shells and subsequently modified with KOH. The adsorbent obtained through this procedure was used to remove ciprofloxacin from aqueous systems. Fourier Transform-Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), elemental, X-ray Photoelectron Spectroscopy (XPS), Brunauer–Emmett–Teller (BET) and Zeta analyses were used to characterize the adsorbent. The surface area, in particular, was found to be a very remarkable value of 2730 m2/g. The conditions of the adsorption experiments were optimized based on interaction time, adsorbent amount, pH and temperature. Over 99% success was achieved in removal operations carried out under the most optimal conditions, with an absorption capacity of 884.9 mg·g−1. In addition, the Langmuir isotherm was determined to be the most suitable model for the adsorption interaction.

“…On the contrary, according to the single-layer adsorption capacities and correlation coefficients obtained by using the other four linear expressions of the Langmuir model, it is seen that the Langmuir-1 isotherm better matches the experimental Data [34]. This result shows that adsorption takes place in a single layer and is homogeneous [45,46]. Freundlich's constant (KF) depending on the adsorption capacity ranged from 265.58 mg/g to 418.56 mg/g with the temperature range studied.…”

Antibiotics are among the most critical environmental pollutant drug groups. One of the methods used to remove this pollution is adsorption. In this study, activated carbon was produced from the pumpkin seed shell and then modified with KOH. This adsorbent obtained was used in the re-moval of ciprofloxacin from aqueous systems. Fourier Transform-Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), elemental, X-ray Photoelectron Spectroscopy (XPS), Brunauer-Emmett-Teller (BET) and Zeta analyzes were used for the characterization of the ad-sorbent. In particular, the surface area was found to be a very remarkable value of 2730 m2/g. The conditions of the adsorption experiments were optimized based on interaction time, adsorbent amount, pH and temperature. Over 99% success has been achieved in removal works carried out under the most optimized conditions. In addition, it was determined that the Langmuir isotherm is the most suitable model for the adsorption interaction.

Mason pine-derived hydrochar (MPHC), cedarwood-derived hydrochar (CHC), bamboo-derived hydrochar (BHC), coconut shell-derived hydrochar (CSHC), pecan shell-derived hydrochar (PSHC), wheat straw-derived hydrochar (WSHC), maize straw-derived hydrochar (MSHC), and rice straw-derived hydrochar (RSHC) were synthesized by hydrothermal carbonization (HTC). The physicochemical properties of these hydrochars were characterized by various techniques, and the adsorption behavior of methylene blue (MB) on hydrochars from an aqueous solution was also investigated. The characterization results suggested that the hydrochars possessed various oxygen-containing functional groups (e.g., ether and hydroxyl groups, etc.). Thermodynamic parameters demonstrated that adsorption was spontaneous for all produced hydrochars. The adsorption was endothermic for CHC, BHC, CSHC, PSHC, WSHC, MSHC, RSHC, and exothermic for MPHC. The Langmuir model best described the adsorption process. MB adsorption capacity is ranked as MPHC > PSHC > CSHC > CHC > MSHC> WSHC > RSHC > BHC. The saturated adsorption value for MB on these hydrochars at 15 ℃ was 155. 14, 109.24, 93.15, 91.71, 88.11, 86.36, 70.01, and 64.43 mg/g, respectively; the difference in adsorption value indicates that the type of biomass affects MB adsorption. This high adsorption capacity for MB suggests that the produced hydrochars could be utilized as a promising new adsorbent in wastewater treatment.
