Activated Carbon Nanoparticles as Adsorbent to Remove the Cadmium Ion from Aqueous Solution: Thermodynamic Study

Abstract

Human activities such as fossil fuel burning, car exhaust, mining, agriculture, and the incineration of solid and liquid wastes all contribute to water pollution by heavy metals, therefore this water poisoning poses a threat to living beings. To minimize the pollution of the natural waters, As the adsorption process of metal in solutions, it is critical to identify effective strategies for getting rid of these toxins. This study involves the characterization and synthesis of novel activated carbon nanoparticles (AC) from natural sources (barley) and is applied in an adsorption study to remove cadmium metal. (AC) characterization using XRD, SEM and it was nanoscale in size and particle-like in shape also BET for specific surface area nitrogen adsorption isotherm nitrogen) 718.01 ) and Average pore diameter as (16.851(Å)), from the adsorption experimental data, the results are best described by the Freundlich isotherm model, which has an adsorption removal 76.86% with exothermic process.

Study the degradation and photocatalytic activity of the methylene blue dye by mixing the Aloe vera extract with rust iron oxide nanoparticle

“…The percentage of degradation MB dye that is degrading Fe 3 O 4 NPs synthesized using aloe vera extract at 300 o C deposition on glass substrate by drop-casting method is higher than the percentage of degradation MB dye that is degrading Fe 902 O NPs using aloe vera extract at 600 o C, as explained in figure 9 (B) (Wilhelm et al, 2020). The constant rate Kph of MB dye of Fe 3 O 4 NPs synthesized using the aloe vera extract at 300 o C deposition on glass substrate by the drop-casting method was determined to be 0.099 min −1 , but the constant rate Kph of MB dye of Fe 902 O NPs was 0.029 min −1 , as shown in figure 9 (C) (Ahmad et al, 2015;Brown, 1987;Ibrahim et al, 2013;Oelmüller, 2018;Reaad et al, 2023;Xu et al, 2012). IONPs are covered by the numerous phytochemicals found in plant material.…”

Effect of synthesis conditions on the porous texture of activated carbons obtained from Tara Rubber by FeCl3 activation

“…Owing to their unique properties, such as high specific surface area and pore volume, as well as the substantial advantage of controlling their porous structure through the selection of suitable raw materials and production technologies, microporous carbonaceous adsorbents are in common use in industrial processes and everyday life. Activated carbons are used mainly for adsorption processes 1 – 5 , although they are also widely used in catalysis, both as mass catalysts 6 – 9 or as catalysts supports 10 – 13 or in energy applications 14 , 15 . They are usually obtained by physical activation preceded by carbonisation, or by chemical activation 16 .…”
