Remarks:

Sodium Sulfate also widely used as LAUNDRY CHEMICALS.
 

Use of Sodium Sulfate Anhydrous :
  • Surfactants, decontamination, foaming, wetting agents, etc.
  • Relatively low-level ion pair reagents, when the requirements are not high, cheaper than heptane, sodium pentane sulfonate.
  • As a raw material, modification of materials.
  • Capillary electrophoresis analysis, additives, generally used as a molar solution .
  • Other analytical methods will also be used, such as flow column analysis.
