“…Research conducted by Baunsele and Missa (2020), using Fe2O3 impregnated corncob activated carbon adsorbent is available Langmuir isotherm with Langmuir constant and adsorption capacity/the maximum (qm) obtained were 0.49 and 15.38 mg/L, respectively. The research using coconut coir adsorbent showed that the adsorption of methylene blue using coconut coir adsorbent followed the model pseudo second order reaction kinetics with adsorption constant rate of 0.01 gram mg -1 minute -1 (Ristianingsih et al, 2020). This indicates that the absorption capacity of methylene blue by CHMFKR is greater.…”

Adsorption kinetics is part of adsorption and discusses the adsorption rate of an adsorbent on the adsorbate. Adsorption kinetics has an equation to determine the rate constant of adsorption, namely the pseudo-first order and pseudo-second order. In this study, methylene blue was adsorbed using a C-4-hydroxy-3-methoxyphenylcalix[4]resorcinarene (CHMFKR) adsorbent. The aim of this study to determine the effect of process parameters (concentration, pH, and processing time) on the process adsorption, with the Langmuir and Freundlich adsorption isotherm model approach, and to determine the adsorption kinetics of methylene blue with CHMFKR. Ten mL of methylene blue solution with various concentrations of 5, 6, 8, 10, and 11 ppm with a solution pH of 7 was added to as much as 0.001 gram of CHMFKR adsorbent and stirred at 600 rpm for 40 minutes. The solution was measured, and its absorbance was measured using the UV-Vis Spectrophotometer. The results show that the adsorption kinetics follow pseudo second order with an adsorption rate of 0.7217 ± 0.4 g/mg.s. The adsorption isotherm follows the Langmuir equation, and the maximum adsorption amount is 114.94 ± 2.04 mg/g.

“…One common method to reduce dye pollution is adsorption. Adsorption is cost-efficient and ecofriendly because the materials used can come from natural samples or environmental waste, and this method is easier to do, has high efficiency, and is widely used [9,10].…”

The waste of palm sugar fiber from the home industry of glass noodles reaches 25 tons/day and has not been used economically regardless of the content of its cellulose about 52%. With the high content of cellulose, palm sugar fiber can be synthesized as a functional adsorbent to overcome the environmental issues that arise. The synthesis of nanofiber was carried out in several steps including washing the sample to remove dirt, synthesizing using a chemical approach (NaOH, HCl, NaClO2, and CH3COOH), and modifying the nanofiber surface with 3% and 5% cobalt oxide. The characterization showed that palm sugar fiber was successfully transformed into nanofiber based on XRD, FTIR, dan SEM results. The removal of dye waste was observed, showing that the adsorption capacity of nanofiber modified with 5% cobalt oxide calcined at 400 °C for 2 hours was suitable for methylene blue removal compared to congo red up to 9.162 mg/g. The adsorption followed the pseudo-second-order kinetic model with Langmuir adsorption isotherm.
