4. Conclusion
In summary, MIL-100(Fe) exhibited excellent demulsification performance
for the model emulsion. The MIL-100(Fe) preferred to demulsify at acid
and hyperhaline conditions. The amphipathicity micro-domain of
MIL-100(Fe) was important for demulsification. MIL-100(Fe) degraded the
SDS by abstracting the hydrophilic group of SDS. This degradation for
surfactant could erase the potential risk of emulsifying again. At the
practical occasion, MIL-100(Fe) dehydrated the water of 79% from the
crude emulsion within 5 min without any without any other assistive
technologies. Therefore, this study exhibited the potential of
demulsification using MOFs in the area of environmental remediation and
petroleum industry. Additionally, this study could be a guidance for the
development of new demulsifier to against the harsh conditions.
