“…To support the SDGs, the quest for the use of cheap, readily available, efficient, and environmentally friendly adsorbents is crucial. Biochar or carbon materials are one of the effective materials, making them to be well-research [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Several adsorbents have been proposed using agricultural waste, from leaves, seeds, roots, and bark [30].…”

In the need for a sustainable environment and clean water for assisting sustainable development goals (SDGs) in developing countries, this study demonstrates the way how to produce biochar carbon microparticles from tamarind seed waste and investigates the proposal mechanism during the adsorption by comparing results with ten adsorption isotherm models. In short, carbon microparticles (sizes of 500, 1000, and 2000 m) were prepared by carbonizing saw-milled tamarind seeds at 250 C. The adsorption was evaluated in the batch reactor for adsorbing curcumin (as a model of dye). The models confirmed the formation of a layer with physisorption characteristics and binding energy due to the existence of the Van der Waals force. The adsorption profile was also done by varying adsorbent sizes and initial adsorbate loadings. Small-sized adsorbents gave impacts the improvement of adsorption capacity due to the presence of a larger surface area, a larger number of adsorption sites, and additional adsorbate-adsorbate interaction. Fewer loadings of the adsorbate results in less adsorption efficacy due to the less adsorbate-adsorbent contact and interaction. Understanding the processes happening is beneficial for future advances and applications, such as catalysts and adsorbents, particularly concerning the utilization of carbon materials from organic waste.

“…The utilization of carbon as a material in significant applications is widely documented. Carbon is one of the most often used materials (Awan et al, 2017a;Awan et al, 2017b;Awan et al, 2019;Efiyanti et al, 2020;Sambudi et al, 2022;Nandiyanto et al, 2023;N'diaye, 2023). It is because of how well it works in the adsorption process (Anshar et al, 2016).…”

In this study, date-seed-based carbon was prepared and investigated for the adsorption process on the removal of curcumin dye in an aqueous solution. Carbon is prepared by carbonizing date palm seeds for 3 hours at a temperature of 250°C, followed by a grinding and sieving process. The carbon particles were then characterized using a Digital Microscope, sieve test, and Fourier transforms infrared analysis instrument. The adsorption test was carried out through batch experiments at constant pressure and room temperature. The adsorption results were then evaluated using ten adsorption isotherm models, including Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Fowler-Guggenheim, Hill-Deboer, Jovanovic, Harkin-Jura, Flory-Huggins, and Halsey. Carbon-based adsorbent from date palm seed showed an adsorption capacity in the range of 38.759 mg/g with a suitable adsorption isotherm is Langmuir > Dubinin-Radushkevich > Jovanovic > Freundlich > Halsey. Based on the five best-fitted isotherms, the adsorption process runs normally, spontaneously, and favorably, confirming monolayer and multilayer formation occurs on heterogeneous surfaces. Then, the adsorption follows cooperative adsorption with chemical and physical interactions at one time. The research study presents findings on adsorbents synthesized by date palm seeds for water treatment and their potential applications as adsorbents.
