一般描述
硫酸镁七水合物是镁的水合盐。通过电子自旋共振（ESR）光谱研究确定了硫酸镁七水合物中(Cu(H2O)6)2+配合物的自旋哈密顿参数。已经报道了10种水合和无水形式的硫酸镁的拉曼光谱。它们的晶体结构和空间基团已通过拉曼和XRD（X线检查衍射）研究进行了评估。
应用
- Optimization of the fermentation media and growth conditions of Bacillus velezensis BHZ-29: This research utilizes Magnesium sulfate heptahydrate as a crucial micronutrient in the optimized growth medium for Bacillus velezensis, enhancing its bioactivity and efficacy in agricultural biocontrol applications (Shi et al., 2024).
- Research on and Model Analysis of Flexural Mechanical Properties of Basic Magnesium Sulfate Cement Concrete Beams: The study focuses on the use of Magnesium sulfate heptahydrate in the production of magnesium sulfate cement, a material noted for its improved flexural strength and durability, which is critical for sustainable construction practices (Mei et al., 2024).
- Antimicrobial Activity of Bacillus amyloliquefaciens BS4 against Gram-Negative Pathogenic Bacteria: Magnesium sulfate heptahydrate is used here as a component of the growth medium to enhance the production of antimicrobial compounds, illustrating its role in supporting microbial activity with potential applications in biotechnology and pharmaceuticals (Palacios-Rodriguez et al., 2024).
