“…The functional groups on the synthesized carbon can be seen in Table 1. The results of this FTIR spectrum indicate that the carbon from the cempedak shell has functional group suitability with the standard structure of the theoretically activated carbon (-OH, C=C, -CH, and -CO), where each wavenumber of the resulting peak is in the range activated carbon wave (Lewoyehu, 2021). The resulting activated carbon has an absorption pattern with the type of bond -OH, C=C, C-H, and C-O and can then be used as an adsorbent for solutions and gases.…”

Synthesis of activated carbon from cempedak peel waste is carried out to utilize biomass waste. This study aimed to synthesize and characterize activated carbon from cempedak peel waste. The synthesis was carried out by chemical activation using phosphoric acid with a dry impregnation ratio of 1:4 (g sample:g H3PO4). Samples impregnated for 24 hours were then heated at 250℃—and then calcined at 350℃ and 450℃. The XRD and FTIR characterization results indicated that the activated carbon obtained had an amorphous structure and the activated carbon obtained had hydroxyl, carbonyl, and carboxylic groups. Activated carbon with the highest yield was obtained at a temperature of 350, namely 43%. The results of determining the water content of activated carbon obtained are 8.36% at 350 0C and 7.1% at 450 ℃. The value of water content and ash content of activated carbon from the skin of this cempedak fruit has met the Indonesian National Standard (SNI 06-3730-1995). The best-activated carbon yield was at a calcination temperature of 450, with the percentage of adsorption efficiency on methylene blue of 98.88%.

“…Nonetheless, the high cost of producing activated carbon and the difficulties in regenerating it limit its widespread utilization. [161][162][163] Carbon-based nanomaterials such as CDs and graphene have been developed as an alternative to conventional adsorbent materials. Using CDs as adsorbents offers several advantages over graphene materials.…”

“…It is reported that around 80% of the AC around the world is being used in a liquid phase or aqueous solution [135]. The adsorption of pollutants from the solution is an exchange process that mainly depends on the porous structure and surface area of the ACs [16,136]. The adsorption mechanism may be influenced by the electrostatic or non-electrostatic interaction between the solute and the carbon surface.…”

Global warming and water/air contamination caused by human activities are major challenges in environmental pollution and climate change. The improper discharge of a large amount of agro-forest byproduct is accelerating these issues mainly in developing countries. The burning of agricultural byproducts causes global warming, whereas their improper waste management causes water/air pollution. The conversion of these waste materials into effective smart materials can be considered as a promising strategy in waste management and environmental remediation. Over the past decades, activated carbons (ACs) have been prepared from various agricultural wastes and extensively used as adsorbents. The adsorption capacity of ACs is linked to a well-developed porous structure, large specific surface area, and rich surface functional moieties. Activated carbon needs to increase their adsorption capacity, especially for specific adsorbates, making them suitable for specific applications, and this is possible by surface modifications of their surface chemistry. The modifications of surface chemistry involve the introduction of surface functional groups which can be carried out by various methods such as acid treatment, alkaline treatment, impregnation, ozone treatment, plasma treatment, and so on. Depending on the treatment methods, surface modification mainly affects surface chemistry. In this review, we summarized several modification methods for agricultural-waste-based ACs. In addition, the applications of AC for the adsorption of various pollutants are highlighted.
