Abstract

Acid mine drainage is mining waste that contains a lot of sulfate and heavy metals such as Fe and Mn which can cause environmental damage and pollute the ecosystem, therefore it needs to be managed. One way to manage acid mine drainage is with phytoremediation techniques using Purun tikus (Eleocharis dulcis). The ability of Purun tikus to accumulate heavy metals can be known by calculating the bio-concentration factor (BCF) and tranclocation factor (TF). This study aims to determine the value of bio concentration factor (BCF) and tranclocation factor (TF) in rat purun in absorbing Fe and Mn so that it can be used for coal mine acid water management. Sampling was conducted using Convenience sampling method. Analysis of Fe, Mn, BCF and TF levels was carried out using an atomic absorption spectrophotometer. In the study, the bio concentration factor (BCF) value for Fe was 7.53, and for Mn was 30.09. While the value of the tranclocation factor (TF) for Fe is 0.77 or the value of TF less than 1, this indicates that rat Purun in accumulating Fe metal uses a phytostabilization mechanism. Then the tranclocation factor (TF) value for Mn is 1.44 or TF value more than 1, indicating that in accumulating Mn metal, Purun rats use a phytoextraction mechanism.

Abstract

The clean water treatment process changes the physical, chemical, and biological properties of water so that it meets the requirements for use as drinking water or daily needs. The purpose of this research is to analyze the performance of ceramic membranes in processing water from the Kelekar River into clean water using an environmentally friendly microfiltration–adsorption–ceramic membrane integrated process. The research was carried out from January to April 2022 at the Chemical Engineering Laboratory of the Sriwijaya Polytechnic. The sampling location for this research is Kelekar River, Karang Raja Village, East Prabumulih. The main tools and materials are a series of water filters (microfiltration–adsorption–ceramic membrane) and river water. The analysis results show that a series of microfiltration-adsorption-ceramic membrane integrated process water treatment equipment can be used to treat river water into clean water. Based on the analysis of river water quality parameters, such as BOD5, iron (Fe), manganese (Mn), nitrate (NO3-), ammonia (NH3-N), and total coliform bacteria after water treatment were within environmental quality standards. Meanwhile, COD and nitrite (NO2-) were still not meeting the environmental quality standards set by Government Regulation of Republic Indonesia No. 22 of 2021 concerning the implementation of environmental protection and management.

Abstract

Bioethanol is a sustainable fuel product to be an alternative energy source. Therefore, the study aims to observe and analyze the effect of MnFe2O4 coated-chitosan in increasing bioethanol production. This bioethanol was produced from molasses with a high total sugar content of up to 50% with Candida tropicalis as the microorganism. Fermentation is divided into two parts, namely using free C. tropicalis and C. tropicalis immobilized MnFe2O4 coated-chitosan. There was electrostatic interaction between MnFe2O4 and chitosan in 578 cm-1 and 659 cm-1 of FTIR, cubic spinel pattern in XRD, and SEM surface image of C. tropicalis immobilized MnFe2O4 coated-chitosan interaction. These characterization results show very good properties as a biocatalyst. The highest concentration was produced by fermentation using C. tropicalis immobilized MnFe2O4 coated-chitosan about 4.35% with residual sugar of 8.46 g/L. In summary C. tropicalis immobilized MnFe2O4 coated-chitosan have the potential to improve bioethanol products.

Abstract

The present study focuses on the assessment of Hg distribution in both soil and water samples from the small-scale gold mining region of Karang Jaya Sub-district, Musi Rawas Utara Regency, South Sumatra Province. For over 30 years, this region has witnessed persistent utilization of mercury as an amalgam for gold extraction. The investigation encompasses an analysis of total mercury levels in soil samples obtained from Sukamenang, Muara Batang Empu, and Terusan Villages. As a comparative reference point devoid of gold mining activities, the neighboring Muara Lakitan Village was selected. The obtained results indicate a moderate to strong contamination level across the 30 sampled locations based on the Geoaccumulation Index (Igeo), with an average Igeo value of 2.6. Furthermore, Pollution Load Index (PLI) and Contamination Factor (CF) values demonstrate high contamination. Conversely, analysis of river water samples from 30 stations along the Rupit River reveals that most of the samples comply with quality standards (<0.0005 mg/L), with an average value at 0.000322 mg/L; only four stations exhibit total Hg concentrations surpassing regulatory thresholds. All soil and river water samples from the control area (10 stations) exhibited no signs of pollution. Appropriate investments in technology, finance, and technical skills are needed to reduce mercury pollution due to small-scale gold mining activities.

Abstract

This study describes the co-precipitation synthesis of magnetic bentonite-Fe3O4 for photocatalytic degradation of methylene blue and Congo red pigments under visible light. Bentonite-Fe3O4 composites were produced using the mass ratio of 2:1 and 1:1 for bentonite to Fe3O4, respectively. X-ray Powder Diffraction (XRD), Fourier Transform Infra-Red (FTIR), BET surface area, Vibrating-Sample Magnetometer (VSM), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS), and Ultraviolet–Visible Diffuse Reflectance Spectroscopy (UV DRS) were used to characterize the materials. The bentonite-Fe3O4 (1:1) composite exhibited a greater surface area in comparison to the bentonite-Fe3O4 (2:1) composite with a measured value of 106.6 m2/g. It is a superparamagnetic material with a band gap of 2.25 eV and a saturation magnetization of 69.64 emu/g. The photocatalytic degradation of dye using bentonite-Fe3O4 (1:1) with the initial dye concentration of 25 mg/L, volume of 50 mL, catalyst dose of 0.05 g/L, addition of 3 mL H2O2, and 90 minutes of visible irradiation resulted in 94.34% and 98.45% degradation efficiency of methylene blue and Congo red dyes, respectively. The study determined that the most favorable pH for the photocatalytic degradation of methylene blue was pH 11, whereas the optimal pH for Congo red was found at pH 5. For methylene blue and Congo red dyes, photocatalytic degradation followed pseudo-first-order with the constant rates of 0.0356 min-1 and 0.0348 min-1, respectively. After five cycles of use in the photocatalytic process, the catalyst's degradation efficiency fell into below 5%. This research demonstrated that catalysts could be utilized in wastewater treatment technology.

Abstract

This study aims to synthesize bentonite/PDA/Fe3O4@CuO composites as a catalyst for the photodegradation of Methylene blue dye. Composite characterization involves X-ray Diffractometry (XRD), Scanning Electron Microscopy (SEM) with X-ray Energy Dispersion Spectrometry (EDS), UV-Vis Diffuse Reflectance Spectroscopy (UV-Vis DRS), and Vibrating Sample Magnetometer (VSM). Response Surface Methodology (RSM) employs Central Composite Design (CCD) to optimize photodegradation by varying dye concentration, irradiation time, and catalyst dose. The bentonite/PDA/Fe3O4@CuO composites exhibit a saturation magnetization value of 54.82 emu/g and a band gap of 2.1 eV. The optimization revealed that concentration and dose significantly impact the photodegradation efficiency. A quadratic model is suitable for modeling the photodegradation of Methylene blue dye using bentonite/PDA/Fe3O4@CuO composites, as determined by analysis of variance (ANOVA). The optimal conditions for achieving maximum photodegradation efficiency were identified as a dye concentration of 10 mg/L, an exposure time of 90 min, and a catalyst dose of 1.67 g/L. Under these parameters, the photodegradation process exhibited a remarkable efficiency of 100%. The Bentonite/PDA/Fe3O4@CuO composites exhibited strong stability, efficiency, and recyclability. After six photodegradation cycles, there was a 5.18% decrease in photodegradation efficiency. Copyright © 2024 by Authors, Published by BCREC Publishing Group.

Abstract

This study aims to fabricate a NiFe2O4/SiO2/TiO2 magnetic composite to serve as a photocatalyst for the degradation of Congo red dye. The catalyst characterization involved XRD, FTIR, UV-vis DRS, BET, VSM, SEM-EDS, and pHpzc analyses. The performance in degradation was determined by the effect of various variables, including solution pH, dye concentration, and irradiation time. Results revealed that the NiFe2O4/SiO2/TiO2 composite exhibited a crystallite size of 24.56 nm and a bandgap of 2.1 eV. The surface area of NiFe2O4/SiO2/TiO2 was measured at 154 m2/g, exceeding that of NiFe2O4/SiO2 and NiFe2O4, which were observed at 122 and 51 m2/g, respectively. NiFe2O4/SiO2/TiO2 exhibited magnetic properties with a magnetic saturation of 18.55 emu/g. Under optimal conditions (pH 5, initial dye concentration of 20 mg/L, and 90 min of visible irradiation), the degradation efficiency reached 96.86%. It was concluded that the photodegradation was effective, as its efficiency decreased from 96.86 to 92.45% after five reuse cycles. The presence of mineralization was evaluated using total organic carbon analysis, which revealed an 84.60% reduction in carbon content.
