Phenyl SAMMS 2

Description:

The need to develop inexpensive and efficient filtration media is a high priority for researchers, and in turn offers a challenge for finding new, functional, designer materials that have high uptake capacities and selectivity for environmental contaminants. Phenyl SAMMS is one such high uptake, selective binding substrate.

Self-Assembled Monolayers on Mesoporous Supports (SAMMS) are an excellent sorbent material with extremely high surface area. However, the manufacturing costs of SAMMS is quite high, making it impractical for a disposable application and limited in reusable applications. Researchers at UO and PNNL have addressed this issue by developing Phenyl SAMMS, a modified SAMMS that incorporates a Phenyl-active material reversibly bound to the base material. Two important characteristics of the Phenyl-active material are:

1. Its binding characteristics can be adjusted to target different types of contaminants (e.g. metal ions, small organic molecules, or inorganic ions).

2. The reversible binding allows the "bound" Phenyl-active material to be washed away from the SAMMS matrix and new "unbound" Phenyl-active material can be added to the matrix, allowing for regeneration (and reuse) of the SAMMS.
