Abstract

This research aims to synthesize chitosan-graphene oxide (chitosan-GO) material using the hydrothermal method at varying material ratios and adsorption studies on Congo red. Chitosan-GO composites were synthesized with mass ratios of (1:1), (1:3) and (1:5). The synthesized chitosan-GO composite was applied to absorb Congo red dye. The adsorption process is carried out by varying pH, contact time, concentration and temperature. The chitosan-GO composite was characterized using XRD, BET and SEM-EDS. The results of XRD characterization of the chitosan-GO composite with a ratio of 1:1 showed a diffractogram of 2θ = 22.3°, at a ratio of 1:3 the diffractogram angle was 2θ = 22.1°, while the ratio (1:5) of the diffractogram peak obtained was 2θ = 22.8°. The surface area obtained in chitosan-GO composite was 11.60 m2/g. The morphology of the chitosan-GO composite (1:5) is in the form of crystalline lumps with the constituent elements C (65.98%), O (32.68%), Na (0.22%) and S (0.09%). Adsorption of Congo red dye using chitosan-GO composite obtained optimum conditions at pH 7, contact time 50 minutes, Congo red concentration 45 mg/L and temperature 50°C. The adsorption isotherm is in accordance with the Langmuir isotherm model and the maximum adsorption capacity (Qm) is 10.245 mg/g.

Abstract

This study modified current bentonite with zinc oxide (ZnO) and investigated the performance of phenol adsorption. The material bentonite-ZnO was successfully synthesized and characterized with X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), and Fourier transform infrared (FT-IR). The adsorption performance was determined by adsorption equilibrium, kinetics, and thermodynamic parameters. The adsorption, kinetic, and thermodynamic parameters were compared alternatively. The phenol adsorption capacity was obtained from Langmuir and Freundlich adsorption isotherm models, which for bentonite-ZnO was fit with both isotherm models (Langmuir R2 = 0,997 and Freundlich R2 = 0,9515) and was favorable than activated bentonite (n value bentonite-ZnO = 2.389; activated bentonite = 0,898). A kinetic model was tested with pseudo-first-order, pseudo-second-order, and intraparticle diffusion models which bentonite-ZnO and activated bentonite fit in the pseudo-second-order with an excellent agreement (R2 = 0,999). Several thermodynamic parameters such as enthalpy, Gibbs free energy, and bentonite-ZnO have an entropy more than zero (ΔS = 0.008 J/molK), which demonstrated the feasibility and spontaneity (ΔG < 0) and endothermic nature (ΔH = 3,056 kJ/mol) of the phenol adsorption process.

Based on the result data in this article, modified bentonite with ZnO has increased the ability for phenol adsorption than currently activated bentoniteKeywords: bentonite, adsorption equilibrium, adsorption kinetics, thermodynamics model, phenol, bentonite-ZnO

Abstract

This study aimed to synthesize, characterize, and evaluate the adsorption performance of H3PO4-activated carbon derived from durian peel for the removal of Direct Red 80. Durian peel was carbonized in a 750 W microwave oven for three heating cycles of 15 min each with 30 min cooling intervals and then activated using H3PO4 solutions at concentrations of 0.3, 0.4, and 0.5 M. Characterization was performed using Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), and analyses of moisture content, ash content, iodine adsorption capacity, methylene blue adsorption, and surface area determined based on the methylene blue adsorption method. FTIR analysis revealed the presence of O–H, aromatic C=C, and phosphate functional groups, while XRD indicated a predominantly amorphous carbon structure. Activation with 0.5 M H3PO4 produced activated carbon with the best characteristics, including a moisture content of 6.19%, ash content of 3.16%, iodine adsorption capacity of 1192.86 mg/g, exceeding the minimum requirement of SNI 06-3730-1995 (750 mg/g), and a surface area of 71.844 m2/g determined by the methylene blue adsorption method. Adsorption was performed using 0.1 g adsorbent in 50 mL Direct Red 80 solution at 100 rpm. The optimum values obtained for the investigated parameters were pH 2, a contact time of 30 min, and an initial concentration of 30 ppm, with corresponding adsorption efficiencies of 66.72%, 66.72%, and 68.41%, respectively. The adsorption kinetics followed the pseudo-second-order model (R^2 = 0.9916), while the Langmuir model provided the best fit (R^2 = 0.9713). H3PO4-activated durian peel carbon shows potential as a biomass-based adsorbent for textile wastewater treatment.Keywords: Activated carbon, Durian peel, Phosphoric acid, Direct Red 80, Adsorption

Abstract

This study investigated an integrated treatment system combining coagulation, adsorption, filtration, and ceramic membrane processes for songket dyeing wastewater. Textile wastewater is characterized by high color intensity, suspended solids, and organic loads, which can cause serious environmental impacts if discharged without adequate treatment. Coagulation using aluminum sulfate effectively destabilizes colloidal particles, followed by adsorption with activated carbon to remove dissolved dyes and organic compounds. Multimedia filtration and ceramic membrane filtration further enhance pollutant removal through physical separation mechanisms. The integrated system successfully achieved color reduction from 976.5 Pt-Co to 10.6 Pt-Co, TSS reduction exceeding 98%, and COD reduction above 93%, in accordance with Indonesian wastewater discharge standards for the textile industry (KLHK, 2016).Keywords: Songket Wastewater, Coagulation, Adsorption, Filtration, Ceramic Membrane

Abstract

This study aims to determine the effectiveness and increase in absorption of the chitosan-ZnO composite in the process of removing methylene blue when using the photodegradation method with the help of a UV lamp. Chitosan was synthesized from shrimp shell waste composite with metal oxide ZnO. The results of the characterization using XRD obtained the diffraction peak for chitosan at an angle of 2θ, namely 19.85°; 29.43°; 34.76° and chitosan-ZnO composite at an angle of 20.18°; 28.93°; 33.57° The SEM-EDX characterization shows that chitosan-ZnO has small, light-colored grains and more gaps and contains elements of chitosan and Zn. In the FTIR characterization, there was a decrease in intensity at a peak of around 3360 cm-1 which was caused by the chitosan-ZnO composite producing OH groups which reacted with methylene blue dye. In testing the effect of contact time using a UV lamp, there was an increase in the percentage of degraded methylene blue compared to without using a UV lamp. The maximum contact time is obtained at 60 minutes. While testing the effect of methylene blue dye concentration, the maximum absorption concentration was 45 ppm at 60 minutes of contact time. The adsorption capacity of the composite against methylene blue dye without UV light was 18.91 mg/g while using a UV lamp it increased to 20.145 mg/g. Based on this research, the chitosan/ZnO composite can be used quite well as a methylene blue dye remover.Keywords: Chitosan, Chitosan-ZnO, Photodegradation, Adsorption, Methylene blue.
