“…Inorganic materials such as tungsten (WO3) was also used as adsorbents in this study. Detailed information on how the process of converting agricultural waste into carbon and silica and fabrication process of WO3 was presented in our previous studies (Ragadhita et al, 2019;Faindini et al, 2020;Nandiyanto et al, 2020a;Nandiyanto et al, 2017;Nandiyanto et al, 2020e). The adsorbate solution used as an experimental model was curcumin solution.…”

“…The relationship in the adsorption isotherm explains the phenomena and interactions between adsorbate and adsorbent. Generally, the adsorption performance can be predicted by modeling the adsorption isotherm data because the adsorption isotherm model can provide information about the adsorbent capacity, the adsorption mechanism, and the evaluation of the adsorption process performance (Nandiyanto et al, 2020a;Anshar & Raya, 2016). In previous studies, we have performed isotherm analysis on various adsorbent systems (Nandiyanto et al, 2020a;Nandiyanto et al, 2020b;Nandiyanto et al, 2020c;Nandiyanto et al, 2020d).…”

Adsorption isotherm is the most important calculation to predict and analyze the various possible mechanisms that occur in adsorption process. However, until now, most studies only presented the adsorption isotherm theory, and there are no studies that explain the adsorption isotherm thoroughly and in detail from theory to calculation. Therefore, this study contains guidelines for selecting the type of adsorption isotherm to describe the entire adsorption data set, which is featured by the ten most common adsorption isotherms. The steps of how to analyze the two-parameter monolayer adsorption are presented. This study is expected to provide clear and useful information for researchers who are working and studying on the adsorption process.

“…Some of these applications ISSN: 0067-2904 include carbon used for water purification agents, gas purification agents, management of various wastes, and even for absorbing mining products. To produce carbon, organic waste can be used as a prospective raw materials, such as rice husks and rice straws [1,2,[9][10][11], orange peels [12], dragon fruit peels [13], pumpkin seed shells [8,14], mangosteen peels [15], pineapple peels [16], tea leaves [17], walnut shells [18], palm shells [19], coconut shells [20], hazelnut shells [21], date stones [22], and almond shells [23]. The use of waste offers important solutions for environmental problems since it transforms waste into useful products [15].…”

This study aims to evaluate the adsorption isotherm of carbon microparticles prepared from pumpkin (Cucurbita maxima) seeds for adsorbing curcumin (as a model of dye). The results were derived and compared using the kinetics approach based on several standard adsorption isotherm models, namely the Langmuir, Temkin, Freundlich, and Dubinin-Radushkevich models. The second aim is to evaluate the effects of carbon particle size (from 100 to 1000 mm) on the adsorption characteristics. The experimental results showed that the adsorption on the surface of carbon microparticles occurred in monolayer with a physical phenomenon. This is because the active areas are located only on the outer surface of carbon and no surface structure in the carbon is available. This is confirmed by the fact that the produced carbon has less porosity and the pores themselves are mostly produced from the release of inorganic contents during carbon synthesis, while the amount of inorganic content is very less. The confirmation of the adsorption profile was also achieved by testing various sizes of carbon microparticles. Smaller particles have direct impacts on the improvement of adsorption capacity, which is due to the existence of a larger surface area, a larger number of adsorption sites, and additional cooperative adsorption, i.e. adsorbate-adsorbate interaction. Understanding the adsorption phenomena occurring on carbon particles is useful for further developments and applications, such as those of catalysts and adsorbents, especially concerning the production of carbon materials from organic waste.

“…In the CR typical synthesis, lanthanum (III) and nickel (II) nitrate hexahydrate were mixed with glycine in a mole ratio of 1:5:7.2 and dissolved in distilled water under stirring for 1 h. The solution was evaporated at 100°C for 4 h. The combustion was ignited by increasing the temperature to 500°C and hold for 2 h. The heating process is important to remove water and convert some organic components [19]. Prior the reduction step, the obtained black powder was firstly mixed with CaH2 and LiCl in a mass ratio of 1:2:0.9 and heated at 600°C.…”

LaNi5 is widely used in various applications. Many methods to produce LaNi5 particles have been reported but information for the large-scale production, so far, is less available. This study aimed to evaluate the project for the production of LaNi5 particles using combustion-reduction (CR) and co-precipitation-reduction (CPR) methods based on engineering and economic perspective. Engineering evaluation was conducted by evaluating the CR and CPR processes from stoichiometry. For the economic evaluation, several economic parameters were calculated in the ideal condition including gross profit margin (GPM), payback period (PBP), break-even point (BEP), cumulative net present value (CNPV), profitability index (PI), internal rate return (IRR), and return on investment (ROI). For the worst cases in the project, it was done by calculating both the internal problems (i.e., raw materials, sales, utility, labor, employee, fixed cost, variable cost, and production capacity) and the external issues (i.e., taxes and subsidiaries). The engineering analysis provided the information that CR and CPR projects are prospective for being able to be done using commercial apparatuses. The economic analysis from GPM, PBP, BEP, CNPV, and PI showed the positive results, while IRR and ROI showed the negative ones, indicating that the projects are acceptable for large-scale production, but it seems to be less attractive for industrial investors. The analysis also confirmed that the CR process was more prospective than the CPR process. This work has demonstrated the important of the projects for further developments.
