In this study, activated carbon (AC) was prepared from teff grass straw via chemical activation and microwave-assisted pyrolysis. The AC was modified by magnetization followed by it was characterized by particle size, FTIR, XRD , thermogravimetric study, pore size, and magnetic properties. Further...

In order to investigate the main pollution factors of underground drinking water sources in semi-arid agricultural areas in China, and to reveal the threatening influence of pollutants on the normal water security of local society. Single-factor evaluation index, principal component analysis, basic...

As the groundwater pollution is increasing, it is crucial to assess groundwater quality and characterize hydrogeochemistry accurately for long term water supply. In this study groundwater samples were collected from 120 locations from Bahawalpur district and analyzed for electrical conductivity (EC)...

For the copper-containing electroplating wastewater generated by a semiconductor company, the recovery of copper salts by progressive freeze crystallization and its process parameters were experimentally optimized and studied. Based on the results of single-factor experiments, according to the...

This study focuses on extraction of Boswellia sacra resin essential oil that was performed using the hydrodistillation method, resulting in a yield of 2.45%. Phytochemical screening of the essential oil provided information about its major compounds, which include terpenes and anthocyanins. To...

It has been suggested that the global warming due to an increase in green house gas concentrations could lead to extreme climate events, such as precipitation extreme and droughts. This study is designed to analyze trend in the long-term time series of preciptation extreme in Kalimantan, focusing on...

It is now possible to measure the biogenic amines histamine, tryptamine, putrescine, cadaverine, spermidine, spermine, and tyramine in an easy, accurate, and selective manner. Dansyl chloride was used to purify the analytes, and high-performance liquid chromatography with detection of fluorescence...

Banda Aceh City and Aceh Besar Regency are two of the areas experiencing rapid population growth and increased waste production, including plastics. The areas are directly adjacent to the coast, and the generated plastic waste has the potential to pollute the sea and fish. Therefore, this research...

Sediment is a source and sink of heavy metal contaminants in wetlands. In this study, sulfate-reducing bacteria (SRB) were used for the bioremediation of sediments from wetlands affected by acid mine drainage. The sediments were inoculated with SRB to study their influence on both the solution and...

An Anaerobic membrane bioreactor (AnMBR) was applied for treating wastewater of a seafood processing factory in Vietnam. However, Chemical Oxygen Demand (COD), Total Phosphorus (TP), and Total Nitrogen (TN) values of the AnMBR effluent were 250.43 mg/l, 19.96 mg/l, and 62.65 mg/l, respectively, and...

In this study, zinc oxide (ZnO) films have been electrochemically deposited on stainless steel and its photocatalytic activity on the degradation of BR 18 dyes was tested. The effects of different electrodeposition conditions such as deposition potential and deposition time on the nanostructures of...

Hydrothermal liquefaction (HTL) is involved in concurrently treating both sewage water and generating biofuels. It involves the analysis of various operating parameters, such as pressure, catalyst temperature, and reaction time, to determine the productivity and physiochemical properties of the...
