MORALES, C. J.; RIEBEL, U.; ZAVARCE, L.  y  GUZMAN, N. M.. Improving emulsion separation: the collector material concept. Lat. Am. appl. res. [online]. 2010, vol.40, n.3, pp. 241-248. ISSN 0327-0793.

A variety of materials have been used to investigate their applicability as so-called collector materials to improve the destabilization and separation of water in oil emulsions stabilized by a nonionic surfactant. The emulsion destabilization degree was determined by the extent of water and oil separated after centrifugation. The recovery of both phases was strongly dependent on the nature of the material, material/emulsion ratio, particle size, and contact time. By varying conditions, it is possible to increase the separation of water from 0% (without material) up to 95%.
