Abstract

MIL-100(Fe) was prepared and subsequently used to remove crystal violet dye from aqueous solutions simulating dye-containing wastewater in the environment. In the future, it is aimed that MIL-100(Fe) can be used in managing dye-containing wastewater in the environment and reducing the negative impacts it can cause. Here, MIL-100(Fe) fabrication needs to be optimized to obtain optimum process conditions, which are environmentally friendly and can produce MIL-100(Fe) with the best characteristics. This study focused on optimizing the fabrication of MIL-100(Fe), which is a type of MOF with good chemical stability, thermal stability, and flexible structure. In this study, the room-temperature fabrication of MIL-100(Fe) was established using a ligand-to-metal molar ratio of 0.95 and an acetic acid concentration of 5.1 vol% for 6.2 h. The optimum MIL-100(Fe) was tested for crystal violet removal and provided an optimum removal capacity of 182.66 ± 3.81 mg/g. Statistical approaches are used to investigate the independent parameters and their interactions contributing to MIL-100(Fe) formation.

Abstract

Increasing concern about sustainability and environmental issues caused by the massive amount of solid biomass waste in Indonesia has driven efforts to develop new products for various endues applications in energy, environment, and health sectors. This study uses coconut husk as the cellulose source to fabricate magnetic cellulose (MC) via coprecipitation with iron chloride salts. Combining cellulose with magnetite nanoparticles aims to improve the removal rate of synthetic dye as the latter provides high catalytic activity in the Fenton degradation process to eliminate persistent pollutants. The paramagnetic characteristics that MC possesses also make them quickly recovered after use. The adsorption capacity is found at 252.2 mg/g (pH 7, temperature of 30°C, the dye initial concentration of 100 ppm, and the precursor mass ratio of 1:4.8:25) for Rhodamine-B. The dye mineralization in this condition also reaches 50%, indicating that this adsorbent can be used as an efficient material to adsorb and degrade dye from an aqueous solution. This magnetic adsorbent will be of immense potential application for removing organic contaminants, particularly synthetic dyes, due to its good performance, simple separation, and ability to perform both adsorption and degradation processes simultaneously.

Abstract

Seiring dengan berkembangnya teknologi dalam proses industri dan dihasilkannya inovasi-inovasi baru yang mendukung terbentuknya produk-produk baru, maka salah satu produk samping adalah bertambahnya jenis jenis limbah yang cukup kompleks untuk dapat diuraikan. Metoda AOP (Advanced Oxidation Process) dimana salah satunya adalah Proses Fenton menjadi salah satu pilihan dalam menangani jenis limbah yang cukup kompleks. Proses Fenton dengan menggunakan katalis heterogen, diantaranya menggunakan katalis padat memiliki keunggulan dalam aplikasinya. Penggunaan magnetic nanoparticles berbasis Fe3O4 memungkinkan proses Fenton berlangsung secara efektif dan efisien dengan memungkinkan untuk katalis dapat di recycle. Magnetic nanoparticles (Fe3O4) memiliki keterbatasan dalam hal stabilitas karena mudah teragregasi. Untuk memaksimalkan manfaat yang diperoleh dari magnetic nanoparticles (Fe3O4), maka pembentukan komposit material antara mesoporous silica materials dan magnetic nanoparticles (Fe3O4) menjadi pilihan utama. Artikel ini akan memberikan review singkat berkaitan khususnya terhadap: proses Fenton, mesoporous silica nanoparticles (MSN) dan bagaimana membentuk komposit keduanya untuk meningkatkan reaksi Fenton.
