Abstract
Described herein are passive samplers, making of such samplers, and methods of use. In an example embodiment, a passive sampling membrane comprises, for example, a continuous mesoporous sequestration media having a sequestration phase and a support membrane configured to support the sequestration phase. The sequestration phase may include a hydrophobic region and a hydrophilic region. The continuous mesoporous sequestration media may be configured to simultaneously sequester polar and non-polar organic substances.
Claims16
A passive sampling membrane, comprising:
- a continuous mesoporous sequestration media comprising a sequestration phase and a support membrane, the support membrane being configured to support the sequestration phase,
- wherein the sequestration phase comprises a hydrophobic region and a hydrophilic region,
- wherein the continuous mesoporous sequestration media is configured to simultaneously sequester polar and non-polar organic substances,
- wherein the sequestration phase is a polymer,
- wherein the polymer includes the hydrophobic region and the hydrophilic region, wherein the hydrophobic region corresponds to a hydrophobic monomer and the hydrophilic region corresponds to a hydrophilic monomer,
- wherein the sequestration media is an in-situ formed continuous mesoporous phase embedded in the support membrane being a microfiber membrane, and
- wherein the passive sampling membrane has no energy input.
