Abstract

SINTESIS DAN KARAKTERISASI MATERIAL HIBRIDA Mg/AL-LDH TERIMOBILISASI ASAM PARA HIDROKSIBENZOAT. Telah dilakukan sintesis dan karakterisasi material hibrida Mg/Al-LDH terimobilisasi APHB. Mg/Al-LDH terimobilisasi APHB disintesis melalui sintesis tidak langsung dimana APHB diadsorpsikan pada material Mg/Al-LDH. Optimasi sintesis material hibrida dilakukan dengan mengamati pengaruh konsentrasi molar APHB dan pH sintesis. Padatan hibrida hasil sintesis dikarakterisasi dengan spektrometer XRD dan FTIR.Hasil penelitian menunjukkan bahwa sintesis Mg/Al-LDH terimobilisasi APHB optimum dilakukan pada pH 7. Berdasarkan model non linear isoterm Langmuir, diperoleh kapasitas Mg/Al-LDH untuk mengibolisasi APHB adalah 62,16 mg g-1, yang artinya per gram Mg/Al-LDH mengandung 62,16 mg g-1 APHB, dengan nilai konstanta Langmuir (Ka) sebesar 0,31 L mg-1. Hasil karakterisasi menggunakan XRD menunjukkan bahwa nilai parameter kisi a, kisi c dan basal spacing d003 hibrida Mg/Al-LDH terimobilisasi APHB masing-masing 3,06; 23,70 dan 7,09 Å, dimana APHB berada di permukaan luar lapisan hibrida. Hal ini juga didukung oleh hasil identifikasi melalui spektroskopi FTIR bahwa terdapat terdapat gugus-gugus fungsi spesifik asam para hidroksibenzoat di material hibrida tersebut

Abstract

Synthesis of p-hydroxybenzoic acid (PHBA)-intercalated Mg/Al-LDH and PHBA-immobilized Mg/Al-LDH have been conducted. PHBA-intercalated Mg/Al-LDH hybrid was synthesized by co-assembly process of Mg/Al-LDH nanosheets and PHBA anions. PHBA-immobilized Mg/Al-LDH was prepared by indirect synthesis, where PHBA anions were attached on surface of the Mg/Al-LDH material. Characterization by X-ray Diffraction showed that the PHBA-intercalated Mg/Al-LDH hybrid has the lattice parameter of a=3.02 Å, lattice parameter of c=46.77 Å and basal spacing d003=15.14 Å, where PHBA has been intercalated in interlayer of the hybrid. The PHBA-immobilized Mg/Al-LDH has lattice parameter of a=3.06 Å, lattice parameter of c=23.70 Å and basal spacing d003=7.90 Å. The analytical result confirmed that PHBA has been attached on surface of the hybrid for PHBA-immobilized Mg/Al-LDH. The optimum 10 mL of [AuCl4]‾ 100 mg L-1 removal condition of both hybrids were reached at pH 3. The optimum interaction time of [AuCl4]‾ and PHBA-intercalated Mg/Al-LDH hybrid was 250 minutes, respectively, while that for [AuCl4]‾ and PHBA-immobilized Mg/Al-LDH was 150 minutes. Removal of [AuCl4]‾ by PHBA-intercalated Mg/Al-LDH hybrid followed pseudo second order kinetic, whereas by PHBA-immobilized Mg/Al-LDH followed pseudo first order kinetic. Characterization using stereo photomicroscope confirmed that [AuCl4]‾ could be reduced  to Au  metal by both hybrids.

Abstract

This study aimed to determine the effect of sorbitol addition into cellulose acetate-chitosan bioplastic and its biodegradation properties. Cellulose was isolated from the pulp of sugarcane bagasse and acetylated to be cellulose acetate. Cellulose acetate was characterized by FTIR, the results of FTIR characterization contained C=O and C-O functional groups with wavenumbers of 1644.99 cm-1 and 1059.86 cm-1 which indicated the formation of cellulose acetate. Cellulose acetate-chitosan bioplastic and cellulose acetate-chitosan-sorbitol bioplastic has been successfully synthesized and characterized. The results of FTIR characterization showed that bioplastics had C=O and C-O functional groups at wavenumbers of 1644.99 cm-1, 1059.86 cm-1 which was indicated as cellulose acetate and  N-H functional group at wavenumber of 1559.66 cm-1 which was indicated as the presence of chitosan in bioplastics and there is an increase in absorption intensity of the O-H functional group which indicates that sorbitol has been successfully added to bioplastics. The addition of sorbitol could improve the percent of elongation from 14.0635% to 19.9379% and decrease the tensile strength from 6.3049 MPa to 0.6309 MPa. It also could increase water absorption from 16.68% to 88.73%, and could accelerate the bioplastic degradation process from 24 days to 8 days.

Abstract

ADSORPTION OF URANIUM SIMULATION WASTE USING BENTONITE TANIUM DIOXIDE. Bentonite is a clay material of high surface area that have galleries within its structure. Bentonite that is modified with TiO2 will have high adsorption capability. In this study, natural bentonite and bentonite:TiO2 were characterized with FTIR, XRD and BET instruments to determine functional group, basal spacing, and specific surface area. This study also investigates the adsorption of bentonite:TiO2 in various environmental factors, such as pH (pH 1, 3, 5, and 8), contact time (10, 20, 30, 40, 50, 60, 70, 90, and 120 min), and initial uranium concentration (20, 40, 60, 80 ppm), and their influences on adsorption capacity, and determine the kinetics equation and adsorption isotherm. Based on FTIR analysis, a decrease in the band of O-H bond from water molecule was observed, which indicates the presence of TiO2 in bentonite interlayer structure. The XRD characterization of bentonite:TiO2 does not show diffraction peak in 001 plane. This is due to delamination of bentonite interlayer structure. Delamination is caused by the presence of TiO2 in large quantities, thus damaging the bentonite interlayer structure into irregular sheets. Bentonite as sheets will cause the basal spacing to increase and it is anticipated that XRD will find it difficult in detecting the 001 plane at a low 2 theta angle. The surface area of bentonite:TiO2 has increased by 12.04 m2/g. The maximum adsorption capacity of U(VI) took place at pH 5.0 for 70 minutes contact time and uranium concentration of 60 ppm. In this study, the adsorption kinetic and adsorption isotherm are pseudo second-order kinetic and Langmuir isotherm. The kinetic constant and maximum adsorption capacity of bentonite:TiO2 are 0.075 g/mg.min and 5.848 mg/g respectively.Keywords: Bentonite, TiO2, Adsorption, Uranium

Abstract

The synthesis of chitosan-modified silica-coated iron oxide magnetic material (Fe3O4/SiO2/Chitosan) via the sol-gel process addresses the need for enhanced stability and functionality in various applications. Coating iron oxide magnetic material with chitosan-modified silica is a common strategy to improve biocompatibility and performance. This study investigates the synthesis of Fe3O4/SiO2/Chitosan using sodium silicate as the silica precursor. The synthesis involved sonication of Fe3O4 and sodium silicate for 5 min, followed by adding chitosan in 4% acetic acid with continuous stirring. The mass ratio of Fe3O4:SiO2 was fixed at 0.5:0.73, with varying chitosan masses (0.025, 0.050, and 0.075 g). Characterization techniques used included Fourier-Transform Infrared Spectroscopy (FTIR), X-ray powder Diffraction (XRD), and Thermogravimetric analysis (TGA). The product with the highest mass yield was further analyzed. The variation in the amount of chitosan in the conducted research aimed to determine the optimum chitosan mass that could still bind to the silica framework. Magnetite was confirmed as the primary composition, with the addition of chitosan and silica functional groups observed through vibration absorption characteristics. Thermogravimetric analysis showed differences in decomposition patterns between samples. The optimal chitosan content for characterization was determined at 0.050 g. Future applications might include enhanced adsorption processes owing to the optimized structure and composition of Fe3O4/SiO2/Chitosan nanoparticles.

Abstract

Fly Ash and Bottom Ash (FABA) is the waste from burning coal in coal-fired power plants and consists of chemical compounds, such as SiO₂, Al₂O₃, Fe₂O₃, and CaO. This waste poses an environmental challenge and an opportunity for the construction industry. This study conducted a comparative analysis of the composition of FABA from several coal-fired power plants in Indonesia and other countries, such as Thailand, China, Malaysia, France, Italy, and Portugal. In particular, this study assessed the XRF data from several other references. The XRF test data showed significant variations in the FABA content, influenced by coal type, combustion method, and emission management technology. The high SiO₂ content in the Cirebon and Teluk Sirih coal-fired power plants showed potential for pozzolanic applications. Meanwhile, the high Fe₂O₃ in Tanjung Enim and Sudimoro had the potential for metallurgical applications. In addition, the high CaO content of Teluk Sirih allowed its use in lime production and soil stabilization. However, high levels of SO₃, especially in Cirebon, required more attention in processing because of its impact on concrete quality and environmental pollution. With proper processing, FABA could be a valuable resource in various industries, reducing reliance on natural raw materials. This study highlighted the potential for the sustainable use of FABA and proposed management measures to address environmental challenges. The optimal use of FABA reduced negative environmental impacts and opened up significant economic opportunities, supporting the circular economy in the energy and construction sectors.
