Sodium lauryl sulfate (K12) is white or light yellow powder or liquid with a slight greasy smell. Easily soluble in water, it can reduce the surface tension of aqueous solutions and emulsify oils and fats. It is not sensitive to alkali and hard water, and has good compatibility with anions and non-ions. This product is flammable, irritating, and sensitizing. It is flammable when exposed to open flames and high heat. It decomposes when heated to release toxic gases.
Application of sodium lauryl sulfate (K12) in water treatment:
Sodium lauryl sulfate can be used as a foaming agent, floating agent Agent selection, etc. are used in wastewater treatment.
For example, the printing and dyeing industry usually uses physical and chemical methods (coagulation sedimentation or air flotation) to treat printing and dyeing wastewater. The physicochemical method is a printing and dyeing wastewater treatment method with mature technology, simple operation and management, and low application cost.
In the process of coagulation sedimentation or coagulation flotation, aluminum salt coagulant is one of the most widely used coagulants; magnesium salt coagulant is used in printing and dyeing due to its green and safe advantages. Wastewater treatment has received widespread attention.
Sodium lauryl sulfate has good foaming properties, water solubility and stability in aqueous solutions with a wide pH value, so it is very suitable for use as a flotation agent in coagulation flotation treatment.
