A passive sampling device is provided that is comprised of a member having a first surface and a second surface opposite the first surface and a hole through the member extending from the first surface to the second surface. An adsorbent material is positioned between two mesh members. The adsorbent material allows for efficient and selective removal of organic molecules, such as, for example, perfluoroalkyl substances.

Passive sampler

Provided is a system and method for extracting organic solutes from water with a filter media. The system and method allow for regenerating the filter media following treatment of a water supply containing one or more organic solutes to allow the media to be reused for subsequent water treatment operations. The system and method also allows for regeneration of the displacement fluid for reuse in the regeneration of the media with recovery of at least one or more organic solutes from the displacement fluid. Additionally, the system and method allows for substantially continuous treatment of a water supply and regeneration of a filter media.

Method of treating a material using a sol-gel derived composition

One aspect of the present invention includes a swellable sol-gel composition including a plurality of interconnected organosilica nanoparticles. Another aspect of the present invention includes a swellable composite including a plurality of interconnected organosilica nanoparticles and a particulate material capable of binding to or reacting with a non-polar or organic sorbate. When dried, the sol-gel composition and the swellable composite may be capable of swelling to at least twice their dried volume when placed in contact with a non-polar or organic sorbate.

The present invention relates to a method of making a swellable sol-gel composition that involves the use of a bridged silane precursor. The resulting sol-gel includes residual silanols, which are derivatized with a reagent having at least one silanol-reactive group and at least one alkyl group; and the sol-gel is then dried. Sol-gels of the invention are demonstrated to swell up to about 8-10 times their original volume in the presence of a non-polar sorbate. The sol-gel compositions can be used in a sorbate-activated actuator or in a detector for non-polar sorbates. The sol-gel compositions can further be used to take up non-polar sorbates for purposes of chemical remediation, extraction from aqueous systems or vapor, and chemical sensing.
