Southern Scientific Services Develops Method for Dioctyl Sodium Sulphosuccinate in Wastewater.


To satisfy client requirements, Southern Scientific Services has developed a rapid technique for analysis of the detergent/dispersant dioctyl sodium sulphosuccinate in wastewater.

Di-octyl sodium sulphosuccinate (DOSS) is an ingredient in detergents and dispersant with trade names Manoxol-OT and Corexit. It is an all-purpose wetting agent used in drugs, cosmetics and food industries. It can be used as a laxative.

It has widespread use as a detergent for washing and cleaning. It has been used as a dispersant to break up oil slicks.

Detergents will occur in wastewaters arising from typical commercial washing and cleaning activities.  Wastewater discharge licences will have control limits for components likely to cause pollution in receiving waters. These licence limits will have been imposed by the EPA under the IPPC licensing system and by the local authority for smaller operations.

The rapid technique involves solvent extraction with acetonitrile salting step based on QuEChERS and direct injection into an LC Mass Spectrometer in tandem mode. The LCMS run is 15 minutes long. The method detection limit is 10ug/litre. The MS transitions are mass 421.2 to 80.9, and 421.2 to 227.2 as the confirmation ion.
