Summary: The aim of this study was to enhance the biosorption capacity of Abies bornmuelleriana cones for Cd2+ ion removal from aqueous solutions by treating them with 0.01 M NaOH. The biosorption capacities of normal and modified Abies bornmuelleriana cones were compared, and the selectivity study was conducted in the presence of Hg2+ and Cd2+ ions. The removal mechanism of Cd2+ ions was elucidated using various analytical techniques. The Langmuir isotherm and pseudo-second-order model were found to be the most suitable models for describing the biosorption process. Positive delta H degrees indicated an endothermic process, while negative delta G degrees suggested a quick biosorption process at high temperatures. The Langmuir biosorbent capacities of normal and modified bioadsorbents were determined to be 18.4 and 22.1 mg g(-1), respectively. Both bioadsorbents were regenerated using a 0.01 M HNO3 solution for six cycles.

Summary: In this study, a new biosorbent (MNPLanM) was developed by immobilizing Lanmodulin-SpyCatcher on the surface of SpyTag-functionalized magnetic nanoparticles (MNPs) for selective separation and recovery of rare earth elements (REEs) from waste streams. The biosorbent exhibited high adsorption activity and fast kinetics, and the adsorbed REEs could be efficiently desorbed. MNPLanM selectively adsorbed REEs in the presence of non-REEs and showed high stability after multiple adsorption-desorption cycles. Furthermore, MNPLanM effectively concentrated REEs from low-grade feedstocks, achieving a significant increase in REE purity.

Summary: In this study, the researchers investigated the temperature-dependent variations in the char-volatile products derived from sludge and microplastics under different pyrolysis scenarios. They found that the abundance of EPFRs increased exponentially in the 350-450 degrees C range. The formation of EPFRs was found to be temperature-dependent, and microplastics with conjugated aromatic ring structures were more likely to form EPFRs.

Summary: Conversion of sewage sludge to biochar for contaminants removal achieves the goals of solid waste reuse and pollution elimination. However, the understanding of sludge-derived biochar (SDB) for wastewater treatment is still limited. This paper reviews recent studies on the use of (modified) SDB as adsorbents and catalysts for the removal of contaminants from water. It summarizes the effects of modification on the adsorption and catalytic performance of SDB and discusses the challenges and future directions in using SDB for wastewater treatment.

Summary: Despite extensive research on semiconductor photocatalysis, the fundamental aquatic chemistry of these new materials and their environmental implications are poorly understood. In this study, the solubility of BiVO4 and its non-stoichiometric dissolution in different pH ranges were investigated. The solubility and stability of BiVO4 were found to be pH-dependent, with the lowest solubility and highest stability near pH 5. Illumination significantly enhanced the dissolution of BiVO4. Adsorption of dissolved bismuth by BiVO4 solids was identified as the main reason for the non-stoichiometric dissolution. These findings highlight the importance of considering the dissolution of photocatalysts and provide a method to evaluate the environmental stability and risks of other semiconductor materials.

Summary: This study focused on the pyrolysis of sludge and used in-situ infrared/mass spectral probes coupled with signal amplification techniques to analyze the reactions and dynamic variations during pyrolysis. By comparing different samples, the three-stage pyrolysis of sludge and its reaction mechanisms were identified. The generation of reactive intermediates and collision frequency between reactants played important roles in the pyrolysis process, and the order of volatile generation was consistent with the variations of pyrolysis behaviors, reaction models, and surface characteristics of chars.

Summary: This critical review discusses the synthesis methods of nanomaterial adsorbents (NAs) and assesses their scalability for full-scale applications. It also examines the impact of NAs structures on metal adsorption and emphasizes the need to prioritize research to balance production costs and feasibility of desired properties at commercial scale quantities. Furthermore, it suggests the establishment of an evaluation protocol for NAs to consider both adsorption capacity and mass transfer kinetics during material discovery stage and long-term testing in real applications.
