Abstract
A system for abatement of sterilizing gas may include a device package having a device disposed therein and a sterilizing gas abatement member disposed adjacent to the device package. The sterilizing gas abatement member may comprise a lignosulfonate-based materials including sulfonic acid functional groups configured to abate a sterilizing gas.
Claims20
A system for abatement of sterilizing gas, the system comprising:
- a device package having a device disposed therein;
- and
- a sterilizing gas abatement member disposed adjacent to the device package, the sterilizing gas abatement member comprising:
- a lignosulfonate-based material;
- and
- sulfonic acid functional groups within the lignosulfonate-based material;
- wherein the sulfonic acid functional groups are configured to catalyze conversion of a sterilizing gas present adjacent to the device package.
A sterilizing gas abatement system comprising:
- a container configured to hold one or more sterilized devices;
- a sterilizing gas abatement member positioned within or surrounding the container, the sterilizing gas abatement member comprising:
- a porous matrix formed from a lignosulfonate-based material having sulfonic acid functional groups;
- wherein the sulfonic acid functional groups are configured to convert ethylene oxide gas to ethylene glycol.
A method for forming a sterilizing gas abatement member, the method comprising:
- acidifying a lignosulfonate salt to convert sulfonate groups to sulfonic acid groups;
- and
- forming the acidified lignosulfonate salt into a porous structure configured to abate ethylene oxide gas.
