Summary: Amphiphilic carbon nitride (g-C3N4) decorated reduced graphene oxide (rGO) composites exhibit excellent adsorption properties for organic compounds, especially in aqueous media. The presence of amphiphilic g-C3N4 accelerates the adsorption process and enhances adsorption efficiency as water salinity increases. This research highlights the potential of using amphiphilic carbon-based nanomaterials for practical applications in removing aromatic organic molecules from industrial wastewater.

Summary: This review critically investigates the effect of using microwave heating technique on the morphology, surface chemistry, and pore structure of Carbon based, minerals and polymeric adsorbents, as well as the adsorption performance of water pollutants using microwave synthesized adsorbents. Competitive comparisons between adsorbents prepared by microwave and conventional heating techniques are discussed, along with suggestions for future development of microwave prepared adsorbents for water pollutants removal. Further development and investigation are still required for using microwave technology in adsorbents preparation.

Summary: In this study, the adsorption of oxidizable reducing pollutants from aqueous co-product (ACP) onto granular and powdered activated carbon (GAC and PAC) was investigated. The results showed that PAC exhibited higher adsorptive capacity than GAC for COD, boron, copper, and phenol. The adsorption isotherms followed different models for PAC and GAC, and the Free Energy Change (Delta G0) indicated spontaneous reactions for copper and phenol adsorption. This study provides important information for the design of adsorption systems for ACP treatment.

Summary: The rise of the polymer industry has led to the leaching of phthalate esters into the environment, posing a potential threat to living organisms and ecosystems. This study focuses on developing cost-effective adsorbents, specifically biochar derived from peanut hulls, for removing these harmful compounds, using the model pollutant DMP. The different properties of biochars produced at various pyrolysis temperatures were examined to understand their adsorbent properties and performance. The results demonstrated that biochars exhibited chemisorption and multi-layered adsorption, with the highest efficiency observed for BC650 at 98.8%, followed by CAC at 98.6%. The study also identified the dominant mechanisms of adsorption for DMP onto porous biochar as H-bonding, p-p EDA interactions, and diffusion within the pore spaces. Overall, this research offers strategies for synthesizing biochar effectively for the removal of DMP from aqueous solutions.

Summary: Soil and water are important ecosystems for the survival of organisms, but excessive microplastic pollutants can threaten the sustainability of terrestrial ecosystems. Microplastic pollutants have durability and can easily accumulate in aquatic and terrestrial ecosystems, altering the ecology. Various strategies can be used to adsorb, degrade, and break down microplastic pollutants.

Summary: Emerging pollutants (EPs) are toxins with low concentrations but substantial toxicity that have gained attention due to environmental concerns. These trace contaminants can accumulate in various sources and pose a public health risk when they make their way into human bodies. Biochar adsorbents have been used as low-cost and effective means for treating wastewater and removing EPs. However, improvements are needed for the treatment of emulsifiable concentrated water using biochar adsorbents. Modified biochar (mBC) techniques have been investigated to confiscate EPs from effluents, resulting in different impacts and adsorption processes. Therefore, it is important to systematically evaluate and assimilate information regarding the adsorption of EPs by modified biochar.

Summary: This study introduces a simple method to synthesize amine-crosslinked starch (ACS) biosorbent for removing anionic organic pollutants, demonstrating high selective adsorption capacity and fast removal rate. The adsorption kinetic and isotherm behaviors can be well described by the pseudo-second-order and Langmuir models, with ACS showing a high maximum uptake capacity for various pollutants. Moreover, ACS can be easily regenerated and maintains favorable adsorption performance even after multiple reuses.

Summary: This study focuses on the impact of formic acid-based organosolv (FAOS) pretreatment on sugarcane tops (SCT) for biomass fractionation. The best conditions for FAOS pretreatment of SCT were found to be 125 degrees Celsius pretreatment temperature, 90 min pretreatment time, and 1:7.5 solid to liquid ratio. Temperatures and times higher than these values adversely affected SCT fractionation.
