“…The results from the study reveal the potential application of the clay deposit at Krobo (Eastern Region of Ghana) in developing water treatment technologies with enhanced decolorization and adsorption of water-soluble cationic dyes. In addition, this material can be exploited for their potential application in adsorbing toxins as well as in the entrapment of greenhouse gas emissions (Azmi & Aziz, 2019) and may also have potential application in drug delivery.…”

In this study, a clay sample recovered from an archaeological excavation from the Krobo Mountains in Ghana was examined for its potential to decolorize and adsorb cationic methylene blue. The raw and calcined clay samples were characterized with XRD, SEM, FTIR and EDX. The supernatant obtained by washing the raw clay with 70% ethanol solution decolorized methylene blue. The decolorization of methylene blue was independent of calcination temperature up to 300°C. The clay material subjected to calcination temperature at 600°C showed strong adsorption towards cationic methylene blue. The equilibrium adsorption data fitted well with the Freundlich isotherm indicating adsorption unto heterogeneous surface with the interaction between the adsorbed molecules which is not restricted to the formation of a monolayer. The data also fitted well with the Weber and Morris model which described the rate-controlling steps. The intra-particle diffusion was controlled by pore and surface diffusion. In addition, the adsorption data followed a pseudo-second-order kinetic model, indicating a chemisorption process. The results highlight a unique property of the clay material as an effective decolorizing and adsorption agent for the removal of water-soluble dyes from contaminated water bodies.

“…Over the past decade, solid sorbents such as zeolites (Azmi et al, 2019;Ammendola et al, 2019), porous silicas (Guo et al, 2015;Guo et al, 2017), porous aluminas (Sakwanovak et al, 2011;Gunathilake et al, 2016), metal-organic frameworks (Ding et al, 2019;Yu et al, 2017) and porous carbons (Creamer et al, 2016;Guo et al, 2020;Yang et al, 2017) have been extensively explored for CO 2 capture. However, the adsorption capacity of CO 2 on zeolites and porous silicas would be reduced sharply in the presence of water which is inevitable in ue gas, limiting its applied spaces.…”

Activated carbon spheres with high specific surface area and hierarcal porous texture were prepared from polystyrene-based macroreticular resin spheres by air pre-oxidization and steam activation. The as-prepared carbon spheres had a specific surface area of 1274.95 m2 g− 1, total pore volume of 1.09 cm3 g− 1 and micropore volume of 0.47 cm3 g− 1. Moreover, these carbon spheres showed a hierarcal porous texture composed of ultrafine micropores (0.5-1 nm), micropores (1–2 nm), mesopores (10–50 nm) and macropores (50–100 nm). A CO2 adsorption capacity of 2.82 mmol g− 1 for carbon spheres can be obtained at 30 ℃ and 1 atm. Further, after introducing nitrogen-containing functional groups by gaseous ammonia at 600 ℃, these carbon spheres exhibited a high CO2 adsorption capacity of 3.2 mmol g− 1. In addition, excellent cyclic stability, low hygroscopicity and regenerability temperature suggested these carbon spheres were favorable for CO2 capture.

“…In addition, abundant resources of ACs (including: carbon-containing fly ash, resins or biomass) nominate them as a cheap adsorbent [20]. Recently several studies have devoted to evaluate the potential of different waste materials [21,22]. In this way, Bhatta et al [23] developed low cost activated carbons T from Mesua ferrea L. seed cake through hydrothermal carbonization technique.…”

Recently, developing bio-based carbon materials due to the surface chemistry and a large spectrum of pore structures have received much attention. In the present work, a series of activated carbon (AC) adsorbents were synthesized from the compost derived by the mechanical/biological treatment of municipal solid wastes and evaluated regarding their CO 2 uptake. The AC samples were characterized by sulfuric acid and calcination by N 2 at 400 and 800°C. Then, the CO 2 uptake capacities were evaluated by dynamic breakthrough experiments in a temperature range of 40-100°C and pressures up to 3 bar. The presented data were properly described by Langmuir model and it was revealed that the CMSW-S-800 sample, treated with sulfuric acid and activated at 800°C, has the highest CO 2 uptake capacity with an amount adsorbed around 2.6 mol/kg at 40°C. In the next step, a mathematical model has been developed to match the experimental dynamic breakthrough data and design a pressure swing adsorption (PSA) cyclic process to evaluate the capacity and potential of the best AC sample for CO 2 adsorption. The results arising from this work showed a possible route for the application of the compost as a source of activated carbon for the sorption of greenhouse gases.
