Description

General description

Magnesium sulfate heptahydrate is an eco-friendly composite sorbent in macro cellular foams for thermo-chemical energy storage in solar buildings. Its high latent heat capacity and non-toxic properties enhance energy efficiency, promote renewable energy use, and support sustainable building practices. Click here for more information.

Magnesium Sulfate heptahydrate, commonly known as Epsom salt, is a white crystalline solid. It is highly soluble in water, forming a solution that is commonly used in various applications such as bath salts, fertilizers, and as a component in certain medical treatments. However, it is insoluble in ethanol. It is the source of Magnesium and sulfur.

Application

Magnesium Sulfate heptahydrate is found as a salt of high energy storage and sorption capacity. It was embedded in the polymeric matrix to form a foam for energy storage which prevents issue of swelling, agglomeration, and/or deliquescence of the salt during its de/hydration process. [,] Researchers are developing new adsorbents for removing toxic dyes from wastewater using Magnesium Sulfate heptahydrate. It is essential for creating porous MgAl-layered double hydroxide (LDH)/carbon fiber composites and MgFe₂O₄/γ-Fe₂O₃ magnetic microspheres. These composites effectively adsorb Congo red dye through a combination of biotemplating and pollen template.[,]
