Special Issue Information

Dear Colleagues,

In recent years, the demand for clean water and the compromise on the quality of the available water resources has been on the increase due to the global water scarcity and the negative environmental impacts of industrialization and urbanization. Globally, wastewater management professionals have to ensure that the discharged effluent does not compromise the quality and the safety of the receiving water bodies. Given the prevailing water challenges, the development of sustainable wastewater treatment technologies has become evident to achieve the agenda of the Sustainable Development Goals. Among the treatment methods of wastewater, the adsorption process using adsorbent materials emerges as a pivotal area of research due to its safe, efficient, versatile, multi-functional modification ability, reusability, and cost effectiveness in removing pollutants from wastewater. The effectiveness of adsorption technology depends largely on the properties of the adsorbent materials, like their surface area, surface chemistry, the pore size distribution, and specificity in pollutant affinity. In wastewater treatment, the adsorbent materials enhance both the physical and chemical binding of the heavy metals, dyes, organic compounds, and emerging pollutants towards their surface, thereby removing them from the wastewater. Consequently, the optimization of these materials to enhance their adsorption capacity and selectivity is the significant focus of this Special Issue.

This Special Issue on “Optimization of Adsorbent Materials and Their Application in Sustainable Wastewater Treatment” seeks high-quality works that focus on the advances in the development and application of optimized adsorbent materials for the treatment of contaminated water resources. We invite submissions that investigate the innovative synthesis of adsorbent materials, modifications of existing materials performance, and the adsorption efficiency tests of wastewater treatment using optimization techniques.

Topics include, but are not limited to, the following:

  • Optimization of the synthesis of adsorbent materials for pollutant removal from wastewater.
  • Advanced modifications of the natural and synthetic adsorbents for wastewater treatment.
  • Optimization of the composites of green materials for wastewater treatment.
  • Application of advanced analytical techniques to demonstrate the properties of the adsorbent materials.
  • Determination of the optimum conditions of the adsorption process parameters in wastewater treatment.
  • The regeneration and reuse of adsorbent materials capacity in the sustainability of wastewater treatment technique.
  • Determination of the adsorption process mechanisms using optimized adsorbent materials.
  • Application of optimized adsorbent materials in industrial, municipal, and agricultural wastewater treatment.
  • Challenges and opportunities in scaling up adsorbent-based wastewater treatment technologies for practical applications.
  • Application of nanotechnology and nanomaterials in adsorption processes.
  • Systematic insights on the modeling of adsorption equilibrium, kinetics, and thermodynamics.
  • Environmental and economic assessments of adsorbent materials.
  • Integration of adsorbent materials in conventional and innovative wastewater treatment systems.
  • Regulatory and safety considerations in the deployment of adsorbent materials.

This study addresses the environmental and health hazards posed by Pb(II) and iodine, two significant contaminants. The objective was to explore the adsorption of these substances from aqueous solutions using biochar derived from the leaf midribs of the date palm through a slow pyrolysis process. The pyrolysis was conducted in two stages within a vacuum furnace: initially at 300 °C for 1 h followed by overnight cooling, and then at 600 °C with a similar cooling process. The resulting biochar was characterized for its microstructural features and functional groups using scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy. It exhibited a porous structure with large numbers of pores (20 to 50 μm in size) and functional groups including O-H, C-H, and C=C, which are integral to its adsorption capabilities. For the adsorption studies, a 100 ppm Pb(II) ion solution was treated with varying amounts of biochar (20, 40, 60, and 80 mg) for 24 h. In parallel, iodine adsorption was tested, with biochar quantities ranging from 0.1 to 0.4 g/50 mL. Both treatments were followed by filtration and analysis using atomic absorption spectroscopy to determine the remaining concentrations of Pb(II) and iodine. The study also explored the effect of varying incubation periods (up to 30 h) on iodine adsorption. The results were significant; 100% adsorption of Pb(II) was achieved with the addition of 60 mg of biochar per 10 mL of solution. In contrast, for iodine, a maximum adsorption of 39.7% was observed with 30 mg or 40 mg of biochar per 50 mL. These findings demonstrate the potential of date palm-derived biochar as an effective and sustainable material for the removal of Pb(II) and iodine from contaminated water, offering valuable insights for environmental remediation strategies.

Heavy metals such as copper, often discharged from industrial processes and agricultural activities, pose significant environmental and health risks due to their toxicity, particularly in the soluble form of Cu (II). This study investigates the effectiveness of biochar produced from date palm leaf midrib waste via a two-step pyrolysis process, as a sustainable and economical adsorbent for removing Cu (II) from aqueous solutions The biochar was characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET) surface area analysis. Adsorption experiments were conducted to evaluate the effects of pH, adsorbent dosage, contact time, and initial Cu (II) concentration. The maximum adsorption capacity was observed at pH 6, with a capacity of 70 mg/g. The adsorption data were best described by the pseudo-second-order kinetic model, indicating chemisorption as the primary mechanism. Thermodynamic studies indicated that the adsorption process was spontaneous and exothermic, with a Gibbs free energy change (ΔG) of −1.245 kJ/mol at 25 °C, enthalpy change (ΔH) of −15.71 kJ/mol, and entropy change (ΔS) of 48.36 J/mol·K. Reusability tests demonstrated that the biochar retained over 85% of its initial adsorption capacity after five cycles, with capacities of 60 mg/g in the first cycle, decreasing to 52 mg/g by the fifth cycle. This study highlights the potential of biochar derived from date palm waste as an efficient, sustainable adsorbent for the removal of Cu (II) from wastewater, contributing to both environmental management and waste valorization. Future research should focus on optimizing the biochar production process and exploring its application for the removal of other contaminants. Full article
