詳細

Application

• Bioflocculant produced by Bacillus velezensis and its potential application in brewery wastewater treatment.: This study explores the production of a bioflocculant by Bacillus velezensis, assessing its application in treating brewery wastewater. Magnesium sulfate was used as a coagulant aid, significantly improving the flocculation process (Agunbiade et al., 2022).
• Evaluation of the automated micro-solid phase extraction clean-up system for the analysis of pesticide residues in cereals by gas chromatography-Orbitrap mass spectrometry.: This research evaluates an automated micro-solid phase extraction system for analyzing pesticide residues. Magnesium sulfate was utilized for sample clean-up, enhancing the extraction efficiency and accuracy (Hakme and Poulsen, 2021).
• Online supercritical fluid extraction and chromatography of biomarkers analysis in aqueous samples for in situ planetary applications.: This paper discusses a method combining supercritical fluid extraction and chromatography for biomarker analysis. Magnesium sulfate played a crucial role in the extraction process, facilitating the separation of target compounds (Abrahamsson et al., 2019).
• Bioremediation of oily hypersaline soil and water via potassium and magnesium amendment.: The study examines the bioremediation of oily hypersaline environments using magnesium sulfate and potassium. The amendments improved microbial activity and degradation of hydrocarbons (Al-Mailem et al., 2013).
