Description

General description

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.

We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. 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.

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.[,]
