Abstract
A water-insoluble polymeric oxidizing medium is contemplated that has a plurality of polymerized N-pyridinium vinylbenzyl triiodide or tribromide moieties whose pyridinium rings bear two substituents, R1 and R2, that are independently a hydrido or a C1-C4 alkyl group, and correspond in structure to the formula A process for preparing aseptic water and an apparatus useful for carrying out that process, both of which utilize a contemplated polymeric oxidizing
Claims31
A water-insoluble polymeric medium having a plurality of polymerized N-pyridinium vinylbenzyl triiodide moieties whose pyridinium rings bear two substituents, R1 and R2, that are independently a hydrido or a C1-C4 alkyl group, said polymerized N-pyridinium vinylbenzyl triiodide or tribromide moieties corresponding in structure to the formula
A water-insoluble polymeric medium having a plurality of polymerized N-pyridinium vinylbenzyl triiodide moieties in which the triiodide ion content is about 0.1 to about 1.0 moles per liter, said medium being free of water-elutable iodine.
A process for forming an aseptic fluid from a fluid containing microbial contamination comprising the steps of:
- (a) providing a vessel containing a water-insoluble polymeric medium having a plurality of polymerized N-pyridinium vinylbenzyl triiodide or tribromide moieties of the structure
- wherein R1 and R2 are independently a hydrido or a C1 alkyl group;
- (b) introducing to the vessel an influent of microbially contaminated fluid that is clear and free from visible precipitate to contact the insoluble medium;
- (c) maintaining said fluid in contact with said insoluble medium for a time period sufficient for microbes present in the influent to be killed by said triiodide ions and form aseptic fluid;
- and
- (d) discharging the aseptic fluid from the vessel as an effluent.
A process for forming aseptic water from an aqueous solution containing microbial contamination comprising the steps of:
- (a) providing a vessel containing a water-insoluble polymeric medium having a plurality of polymerized N-pyridinium vinylbenzyl triiodide moieties in which the triiodide concentration is about 0.1 to about 1.0 moles per liter;
- (b) introducing to the vessel an influent of microbially contaminated water that is clear and free from visible precipitate to contact the insoluble medium;
- (c) maintaining said water in contact with said insoluble medium for a time period sufficient for microbes present in the influent to be killed by said triiodide ions and form aseptic water;
- and
- (d) discharging the aseptic water from the vessel as an effluent.
An apparatus for preparing an aseptic fluid that comprises:
- a vessel having an inlet, an outlet and a water-insoluble polymeric medium in a polymeric medium-containing region;
- said water-insoluble polymeric medium comprising a plurality of polymerized N-pyridinium vinylbenzyl triiodide moieties whose pyridinium rings bear two substituents, R1 and R2, that are independently a hydrido or a C1-C4 alkyl group, said polymerized N-pyridinium vinylbenzyl triiodide or tribromide moieties corresponding in structure to the formula
- wherein the medium is supported and contained within the medium-containing region.
An apparatus for preparing aseptic water that comprises:
- a vessel having an inlet, an outlet and a water-insoluble polymeric medium in polymeric medium-containing region;
- said water-insoluble polymeric medium comprising a plurality of polymerized N-pyridinium vinylbenzyl triiodide or tribromide moieties in which the triiodide ion content is about 0.1 to about 1.0 moles per liter, and is free of water-elutable iodine;
- wherein the medium is supported and contained within the medium-containing region.
