Since the frozen layer was only about 2 cm thick it only took several days to remove all the water under vacuum. This generated a fine powder of sodium sulfate and allowed the organic compound I ...

A reagent-based treatment method was developed for the removal of sodium dodecyl sulfate (SDS) from aqueous dispersions of single-wall carbon nanotubes (SWCNTs). Based on a survey of various reagents, organic solvents emerged as the most effective at interrupting the SDS:SWCNT interaction without producing deleterious side …

Four types of treatment systems will remove sulfate from drinking water: Reverse osmosis pushes water through a membrane with tiny pores. The membrane stops many contaminants, including sulfate, …

Many facilities prefer to remove sulfates, especially with larger concentrations, by adding hydrated lime (Ca(OH)2), which will precipitate out the sulfate as gypsum. This can be useful for facilities that also have large amounts of heavy metals in their waste because the sulfate can be precipitated out at a pH below what the metals would need ...

Sodium sulfate is used as a fining agent, to help remove small air bubbles from molten glass. It fluxes the glass, and prevents scum formation of the glass melt during refining. The glass industry in Europe has been consuming from 1970 to …

The primary function of anhydrous sodium sulfate is to act as a desiccant, which is a substance used to remove moisture from its surroundings. This quality finds applications in various industries, including pharmaceuticals, …

The sodium sulfate molecule consists of two sodium atoms (Na), one sulfur atom (S), and four oxygen atoms (O). The molecule adopts a highly symmetrical structure, which contributes to its properties and behavior in different applications. Solubility: It is readily soluble in water but not in ethanol.

In order to use a drying agent such as sodium sulfate or magnesium sulfate, the drying agent is just. added to the solution using a spatula then the solution is stirred or swirled or shaken and set aside to. settle for a couple of minutes.
