Summary: The study demonstrated that thermo plasma expanded graphite (TPEG) is an effective adsorbent material for the removal of methylene blue (MB) from contaminated solutions. The optimal adsorption performance was observed at pH 11, with the process mainly related to electrostatic interactions. Increasing temperature resulted in enhanced adsorption capacity, particularly at initial concentrations higher than 10 mgMB/L.

Summary: The presence of nanoparticles in drinking water raises concerns about their potential risks to human health and the efficacy of water treatment plants in removing them. This study examines the efficiency of granular activated carbon (GAC) in removing CeO2 nanoparticles. The results show that GAC has a good affinity for nanoparticles, with higher adsorption capacity and removal efficiency in lake water compared to ultrapure water. The adsorption mechanism is mainly controlled by electrostatic attractions, and mass transfer processes play a role in the removal of nanoparticles in lake water.

Summary: The study focused on preparing activated carbon from low rank Rawdon coal using chemical activation, and investigated the effects of demineralisation on the adsorption capacities of the activated carbons. The results showed that activated carbons produced from demineralised and pre-carbonised samples had higher surface areas and better adsorption capacities than those from raw coal.

Summary: A magnetic expanded graphite (MEG) composite was successfully synthesized using explosive combustion method, with iron oxide nanoparticles (Fe3O4) coated on the expanded graphite. Both Fe3O4 and MEG exhibited magnetic properties, and the adsorption kinetics of methylene blue dye followed a pseudo-second-order model with a maximum capacity of 78.06 mg/g. The Redlich-Peterson isotherm equation was found to best fit the adsorption experiment datasets in this study.

Summary: This study reported a new activated carbon from Atlas oak wood for phenol removal from aqueous solutions. The activated carbon was characterized and its phenol adsorption capacity was evaluated, showing that H3PO4-activated carbon had the highest adsorption capacity. The outcomes suggest the potential development of efficient natural-based adsorbents for pollutant removal from wastewater.

Summary: In this study, carbon fillers of different dimensions (graphite, graphite nano-platelets, and multiwall carbon nanotubes) were incorporated into a matrix of poly (ethylene terephthalate) to form carbon-reinforced polymer composites. Analysis using DMTA and SEM showed that all composites displayed a similar decline in storage moduli during the glassy to rubbery transition. However, storage moduli values at room temperature increased with higher loading of nano-fillers and then decreased due to the formation of agglomerates of nanotubes and/or rolled up of nano-platelets. The carbon nanotubes exhibited greater reinforcement compared to graphite and graphite nano-platelets. PET samples that underwent quenching showed significant changes in their dynamic mechanical properties due to filler addition and cold crystallization.

Summary: Sorption-based thermal storage is an attractive approach for sustainable and cost-effective thermal management and energy storage. However, the low sorption capacity of sorbents has been a challenge. This research investigates the use of MgSO4/bead activated carbon composites for thermochemical sorption heat storage, which showed high heat release and sorption capacity. The composite achieved higher water sorption capacity and thermal energy density due to the highly developed microporosity and high thermal conductivity of bead activated carbon. This research provides a promising low-carbon pathway for efficient thermal energy capture, storage, and utilization.

Summary: The study investigated the equilibrium and kinetics of CO2 adsorption by coconut-shell activated carbon impregnated with sodium hydroxide at 273 K. The CO2 adsorption increased with NaOH loading and exhibited three distinctive regions. The results showed an empirical correlation between effective pore diffusivity, CO2 adsorption, and NaOH loading.

Summary: Pectin/activated carbon microspheres (P/ACs) were prepared through simple gelation and showed good adsorption capacity for Pb2+, making them a potential candidate for heavy metal adsorbents. The adsorption process followed a pseudo-second-order model controlled by film diffusion, with maximum adsorption capacity estimated to be 279.33 mg/g. The mechanism of adsorption may involve ion exchange, electronic adsorption, complex formation, and physical adsorption.

Summary: This study focuses on the production of porous carbon from shaddock peel for environmental treatments. The porous carbon structure and properties were found to be influenced by carbonization conditions and the use of ZnCl2 as a pore-forming agent. By carefully adjusting the carbonization temperature and the mass ratio between ZnCl2 and shaddock peel, the resulting adsorbent showed high adsorption capacity towards methylene blue. This biomass activated carbon adsorbent has potential to be effective and environmentally friendly for water pollution treatment.

Summary: This study examines the adsorption kinetics of activated carbon (AC) adsorbent materials produced from a by-product of African palm processing. The textural characteristics of the adsorbent solids were determined through N-2 physisorption, revealing BET areas between 721 and 1334 m(2)g(-1) and micropore volumes between 0.33 and 0.55 cm(3)g(-1). FTIR was used for chemical characterization, and CO2 adsorption was measured, showing values between 175 and 274 mg·g(-1). The kinetic study suggests that the intraparticle diffusion model best describes the physisorption process.
