Abstract

The utilization of methylene blue dye in the textile industry can have a significant environmental impact due to its high toxicity. To address this issue, a study was conducted on the photodegradation of methylene blue dye using silver nanoparticles (AgNP) synthesized with marigold (Tagetes erecta) flower extract as a bioreducer. This article reports on the synthesis of AgNP and its application in the photodegradation of methylene blue dye. The synthesis of AgNP involved the reduction of AgNO3 with marigold flower extract. Different ratios of marigold flower extract to AgNO3 solution (0.01 M) were used: 1:9, 2:8, 3:7, 4:6, and 5:5. The formation of AgNP was monitored at various time intervals using UV-Vis spectroscopy. The best AgNP sample was measured using a Particle Size Analyzer (PSA). The research results indicated that the optimal conditions were achieved at a marigold extract to AgNO3 ratio of 2:8, with the UV-Vis spectrum showing a peak at a wavelength of 411 nm. The optimum conditions for photodegradation were as follows: AgNP volume of 15 mL, irradiation for 30 minutes, and pH 4. Under these conditions, photodegradation of methylene blue dye achieved a reduction of up to 72.46% from the initial concentration of 100 ppm.

Abstract

Coordination compounds are compounds consisting of a metal atom as a center surrounded by ligands, which are important in applications such as catalysts and pharmacological sensors. Salophen, as one of the organic ligands, is capable of forming complexes with various metal ions. This study uses a computational chemistry approach to model the geometry, electronic properties, and bond vibrations of compound complexes between salophen and Zn(II), Cd(II), and Hg(II) metal ions using the PM6 semiempirical method. Modeling results show that the metal ion radius affects the dihedral angle of salophen, with the largest angle occurring in the complex with Hg(II) ions, while the complex with Cd(II) ions tends to be close to planar. FTIR analysis shows that the vibrational pattern is influenced by the bond length of salophen with metal ions. In addition, the HOMO-LUMO gap energy of the three complexes is also slightly different, with the Zn-salophen complex having the smallest Egap of 0.25709 eV.

Abstract

Composite membranes consist of matrix and filler. The matrices used are C and CP. Meanwhile, the filler used is MMT-CNT. The aim of this research is to improve the properties and performance of composite membranes by reviewing the effect of adding montmorillonite particle filler as a matrix and MM-Carbon as a filler. The membrane was made using the phase inversion method and solvent evaporation. The physical characterization carried out was FTIR, XRD, and SEM. Meanwhile, for characterization of membrane performance, namely swelling, methanol uptake, ion exchange capacity, methanol permeability, proton conductivity, and TGA. The results of this characterization showed that the optimum membrane was found at C 1.96 - CP 0.09/ MMT-CNT. In this membrane, methanol permeability was found to be 2.64x10-6 cm2/s, proton conductivity was 3.352x10-6 S/cm, selectivity was 1.2714 Ss/cm3, and membrane stability at a temperature of 290°C. So the optimum composition is C 1.96 grams, CP 0.09 grams, and MMT-CNT 0.129 grams.

Abstract

Controlled drug release systems (DRS) are a crucial technology in the medical field, and they continue to be developed today. Chitosan is useful in manufacturing-controlled drug release systems due to its non-toxic, biodegradable, and biocompatible properties. However, it has some limitations when it comes to its physical and mechanical properties. Combining chitosan with other materials, such as bacterial cellulose (BC), graphite (Gr), ZnO, and TiO2, can improve its mechanical properties and antibacterial activity. This study aims to synthesize Chi/BC/Gr/TiO2 and Chi/BC/Gr/ZnO composites as drug release systems. When tested with TCH, an antibiotic model, the drug release kinetics of the composite followed the Hixson-Crowell and Korsmeyer-Peppas kinetics models. Additional tests for physical and mechanical properties, as well as antibacterial activity, have also been conducted. Mechanical properties in terms of tensile strength and Young’s modulus in composites with adding Gr, TiO2, and ZnO have higher values than Chi/BC alone. Compared to positive control, both TCH-loaded composites show higher inhibition against S. aureus bacteria. Based on the results of this study, composite Chi/BC/Gr/TiO2 and Chi/BC/Gr/ZnO have potential applications as DRS such as wound dressing.
