The adsorption kinetic study of methylene blue using nano-crystal cellulose made from oil palm trunk was investigated. A sample of 0.08 g of nano-crystal cellulose was used to adsorb 300 mL of methylene blue solution, with a varied stirring speed at 100, 200, and 300 rpm. Meanwhile, the concentration of methylene blue was varied at 1, 2, and 3 mg/L. The experimental results showed that the range of adsorption rate constant was 0.0007–0.0130 m/min. For the thermodynamic study, adsorption temperature was varied at 303, 308, 313, and 318 K. The adsorption capacity values for such temperatures were 10.3389, 10.3802, 10.3614, and 10.3464 mg/g, respectively. It was found that ΔH° value of 0.00742 kJ/mol, ΔS° of 0.7758 kJ/mol K and ΔG° value of −242.81 kJ/mol. Based on the curve-fitting using the Henry, Langmuir, and Freundlich isotherm models, this adsorption tended to the Langmuir isotherm model, where the adsorption formed a monolayer covering the surface of the adsorbent. It was also found that the Langmuir affinity constant (KL) value was 4.560 L/mg, and the maximum adsorption capacity (qm) was 8.590 mg/g.

The disposal of dye wastewater has become a major global concern. Meanwhile, microorganisms have shown high potential in the treatment of wastewater pollutants. In this study, the involvement of the Fenton reaction in the biodecolorization and biodegradation of methylene blue (MB) by the brown rot fungus Daedalea dickinsii was investigated. Subsequently, D. dickinsii is a fungus capable of producing hydroxyl radicals (•OH). This experiment was conducted with an initial MB concentration of 75 mg/L, and different incubation times of 0, 7, 14, 21, and 28 d respectively. The result showed that the Fenton reaction played an important role, and this was demonstrated by the addition of FeSO4 as a Fe2+ source. The removal of MB by D. dickinsii with the addition of Fe2+ reached 91.454% at 28 d in a mineral salt medium. It was higher compared to D. dickinsii culture treatment without Fe2+ addition, 86.427%. Furthermore, the metabolic degradation product was analyzed using LC-TOF/MS and identified as 2-amino-3-hydroxy-5-(methylamino) benzenesulfonic acid and N-(3,4-dihydroxy phenyl)-N-methyl formamide.

“…This research employed a continuous system and the process optimization method on a fixed bed column. In the historical context of utilizing tea waste, previous studies [20,21,22] focused on batch systems to optimize operating conditions, including adsorbent dose, pH, and MB concentration. This research aims to enhance the efficiency of the adsorption process within a fixed bed column.…”

Tea waste is a low-cost alternative material for making adsorbent to remove methylene blue from synthetic dye wastewater perpetually. Optimization of the adsorbent process utilized Response Surface Methodology (RSM) and a continuously operating system in a fixed bed column. The independent variables in the research are X1 (bed height), X2 (contact time), and X3 (flow rate). The dependent variable is Y1 (removal efficiency) with a matrix design by Box-Behnken. The optimum condition of methylene blue (MB) B removal was found at X1=16 cm, X2=90 min, and X3=4 L/min with an adsorption efficiency of 90.45%. After the activation and adsorption of MB dye, the complete FTIR spectrum shows a distinct peak at 2933.7 cm-1. The results of the EDX analysis performed on tea waste reveal the presence of nitrogen (element N) following the adsorption process. This observation strongly suggests that the tea waste has effectively absorbed MB, as nitrogen is a constituent element found in the molecular structure of MB.
