Special Issue Information

Dear Colleagues,

Currently, the situation of water pollution prevention and control worldwide is still serious. Carbon materials have broad research and application prospects in water pollution prevention and control due to their large specific surface area and pore volume, controllable porous structure, and excellent thermal, chemical, and mechanical stability. Carbon materials can serve as efficient adsorbents for removing water pollutants, and can also serve as highly stable catalysts for degrading water pollutants. Especially, agricultural and forestry biomass is an important renewable resource with great potential for development and utilization. It has the advantages of low cost, large reserves, biodegradability, etc. It is an important raw material that can replace fossil resources to prepare multi-functional carbon materials. How to achieve targeted regulation of the surface properties and porous structure of agricultural and forestry biomass carbon materials through green and efficient processing techniques, and then prepare high-performance biomass carbon materials to achieve efficient removal of pollutants in environmental water has become a focus of research in recent years. This Special Issue aims to evaluate and analyze the latest research progress of biomass carbon materials in the field of water pollution prevention and control.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Wastewater treatment and resource utilization;
  • Classification and raw material sources of biomass carbon materials;
  • Preparation and modification regulation of biomass carbon materials;
  • Biomass carbon materials for adsorption and removal of pollutants in water bodies;
  • Catalytic degradation of pollutants in water using biomass carbon materials.

The presence of antibiotics in water environments increases the resistance of bacterial and can also cause irreversible damage to ecosystems and the human body. In this study, disposable bamboo chopsticks were used as raw material to prepare bamboo biochar (BB) via oxygen-limited pyrolysis to remove norfloxacin (NOR) from aqueous solutions. The properties of the BB were explained through the characterization of its SBET, morphology, structure, and functional groups. The effects of the dosage, pH, ionic strength, and water type on the removal of NOR using BB were investigated. The maximum theoretical adsorption capacities (Qmax) of NOR removed by BB at 25, 35, and 45 °C obtained using the Langmuir model were 76.17, 77.22, and 105.19 mg/g, respectively. To facilitate a comparison with other types of biochar, this study also prepared biochar of rice straw, wheat straw, soybean straw, corn straw, rape straw, peanut shell, Eichhornia crassipes, and other biomass raw materials under the same preparation conditions as the BB. The results demonstrated that the removal rate of NOR using BB was the highest under the same adsorption conditions, reaching 99.71%. Biochar from waste disposable bamboo chopsticks can be used for the treatment of new types of pollutants in water bodies, such as antibiotics and other organic contaminants, which will help to achieve sustainable solid waste management.

The global concern about the water pollution caused by heavy metals necessitates effective water treatment methods. Adsorption, with its substantial advantages, stands out as a promising approach. This study delves into the efficiency of Pb(II) removal using metabolically inhibited microbial cultures. These cultures encompass waste-activated sewage sludge (SS), industrially sourced bioremediation microbes (commercial 1—C1 and commercial 2—C2), an industrially acquired Pb(II) remediating consortium (Cons), and refined strains (derived from Cons) of Paraclostridium bifermentans (PB) and Klebsiella pneumoniae (KP). Our findings reveal maximum Pb(II) adsorption capacities of 141.2 mg/g (SS), 208.5 mg/g (C1), 193.8 mg/g (C2), 220.4 mg/g (Cons), 153.2 mg/g (PB), and 217.7 mg/g (KP). The adsorption kinetics adhere to a two-phase pseudo-first-order model, indicative of distinct fast and slow adsorption rates. Equilibrium isotherms align well with the two-surface Langmuir model, implying varied adsorption sites with differing energies. The Crank mass transfer model highlights external mass transfer as the primary mechanism for Pb(II) removal. Surface interactions between sulfur (S) and lead (Pb) point to the formation of robust surface complexes. FTIR analysis detects diverse functional groups on the adsorbents’ surfaces, while BET analyses reveal non-porous agglomerates with a minimal internal surface area. The Pb(II) recovery rates are notable, with values of 72.4% (SS), 68.6% (C1), 69.7% (C2), 69.6% (Cons), 61.0% (PB), and 72.4% (KP), underscoring the potential of these cost-effective adsorbents for treating Pb(II)-contaminated aqueous streams and contributing to enhanced pollution control measures. Nevertheless, optimization studies are imperative to evaluate the optimal operational conditions and extend the application to adsorb diverse environmental contaminants. Full article
