Disclosed are apparatus for delivery of a gas, e.g., carbon dioxide and/or chlorine dioxide, and methods of its use and manufacture. The apparatus includes a sachet constructed in part with a hydrophobic material. The sachet contains one or more reactants that generate a gas in the presence of an initiating agent, e.g., water. The apparatus can also include a barrier layer and/or a rigid frame. In another embodiment, the apparatus is combined with a reservoir that can be used to deliver a gas to the reservoir and, optionally, a conduit. In another embodiment, the apparatus is incorporated into a fluid dispersion system that includes a dispersion apparatus, e.g., a humidifier.

Apparatus and method for controlled delivery of a gas

Disclosed are apparatus for delivery of a gas, e.g., carbon dioxide and/or chlorine dioxide, and methods of its use and manufacture. The apparatus includes an envelope, and a sachet within the envelope that contains reactant, which generates a gas in the presence of an initiating agent, e.g., water. The envelope allows release of the gas from the envelope. In another embodiment, the apparatus includes an envelope and a partition that separates two reactants within the envelope. The envelope allows an initiating agent into the envelope and release of the gas generated by the reactants in the presence of the initiating agent.

The apparatus includes an envelope, and a sachet within the envelope that contains reactant, which generates a gas in the presence of an initiating agent, e.g., water. In another embodiment, the apparatus includes a barrier layer, a sachet layer disposed adjacent to the barrier layer, a reactant disposed between the barrier layer and the sachet layer that generates a gas in the presence of an initiating agent, and an envelope layer disposed adjacent to the sachet layer.

The disclosed invention relates to a method of disposing of mercury-containing wastewater containing mercury-complexing materials, comprising the steps of treating wastewater containing mercury ions with a strong oxidizing agent in a reaction chamber to produce pretreated wastewater by removing an effluent stream of pretreated wastewater from the reaction chamber; and passing the effluent stream of pretreated wastewater through a column packed with a mercury-selective adsorbent material to produce an effluent stream of wastewater having a reduced mercury content. The adsorbent material is a porous resin having immobilized mercury-selective chelating groups bound thereto. A particularly preferred adsorbent material is a crosslinked styrene-divinylbenzene copolymer having immobilized dithiocarbamate groups bound thereto.

Combined oxidation and chelating adsorption system for removal of mercury from water

The present invention relates to a device method and kit for the convenient and rapid isolation and purification of nucleic acids, proteins, peptides, carbohydrates and oligosaccharides from heterogeneous biological samples. The device comprises a membrane assembly comprised of layers of microporous, polymeric membranes functionalized with ion-exchange groups. The device is reusable for like samples, relatively inexpensive compared to currently available separation techniques and is disposable, thereby avoiding cross-contamination of biological samples.

Combustible fuel gas at low or moderate pressure is supplied to an inlet in the top of an upright working cylinder. The working cylinder then is filled with liquid through a bottom liquid inlet to force the gas from the cylinder and direct it into a storage cylinder. A check valve prevents backflow of gas from the storage cylinder as the liquid is drained from the working cylinder and as the working cylinder again is filled with low or moderate pressure gas. The process of filling the working cylinder with liquid to force the gas from it into the storage cylinder and holding the gas in the storage cylinder while the liquid is drained and the working cylinder is refilled with gas is repeated until the gas in the storage cylinder is a desired high pressure, such as 1500 psi or higher. Two working cylinders can be provided so that, as one of them is drained, the other is filled with liquid, such that gas is substantially continuously forced into the storage cylinder until the desired high pressure is achieved.
