DEVELOPMENT OF GREEN OIL SPILL DISPERSANTS COMPOSED OF IONIC LIQUIDS AND NON-IONIC SURFACTANTS

The chemical dispersants have been used extensively for oil spill remediation in the marine environment. However, traditional chemical dispersants are necessary to be replaced with environmentally friendly oil spill dispersants due to their well-known toxicity and limited biodegradability. This research aimed to develop non-toxic and biodegradable formulation with higher dispersion effectiveness for crude oil spill remediation. The aggregation behaviour, dispersion effectiveness and particle size of the dispersed oil droplets of the binary mixtures containing non-ionic surfactants (e.g.,
Tween 80, Span 80) and surface-active ionic liquid (SAIL) 1-butyl-3- methylimidazolium lauroyl sarcosinate [Bmim][Lausar] were determined. The formulation composed of Tween 80, Span 80 and SAILs named ([Bmim][Lausar], and choline myristate [Cho][Mys]) was characterized by its emulsion stability, surface tension and interfacial tension (IFT).
