A method of separating a metal organic framework (MOF) from a solution and associated apparatus. The method comprises: providing a MOF containing solution; contacting the MOF containing solution with an acoustic reflector surface such that, any high frequency ultrasound applied within the MOF containing solution reflects off the acoustic reflector surface; and applying a high frequency ultrasound of at least 20 kHz to the MOF containing solution. The MOF material is substantially separated from solution as aggregated sediment that settles out of solution.

Separation of metal-organic frameworks

A method of extracting recovering oil from vegetable material in which oil bearing material is heated and subjected to sonication at least one frequency above 400 kHz, removing a first yield of oil by decanting and subjecting the retained material to centrifugal separation to separate out a second yield of oil. Preferably the raw vegetable material is passed through a screw press and the obtained material is heated and subjected to the ultrasonic treatment and then allowed to settle for a predetermined period before decanting the oil layer. Preferably two frequencies above 400 kHz are used, one below 1 MHz and the second from 1 MHz. There are many potential transducers arrangements possible for producing standing waves.
