The overall efficacy of microemulsion-based extraction of heavy metals (particularly mercury) from contaminated water involving oleic acid was reported and successfully modeled by Wiencek and coworkers [153,154], who used experimentally determined equilibrium extraction, stripping, and the initial reaction kinetics. This model accurately predicts both the initial extraction kinetics and final mercury extraction equilibrium, Good agreement between theory and experiment on the mechanism of extraction using a microemulsion to that of coarse emulsions has been found. Electrostatic coalescence and butanol addition were evaluated as potential demulsification techniques for recovery of the components from mercury-rich microemulsions [155]. [Pg.290]

Extraction of inorganic mercury by the hydrochloric acid -tetramethyltin procedure is made using milder acidic conditions for methylation. Addition of methanolic tetramethyltin to the initial aqueous phase from the organic mercury extraction effectively produces methylmercury in 85-90% yield after 10 minutes shaking. [Pg.70]
