A device for easy and rapid removal of pollutants from drinking water and other liquids. A method for removing a pollutant from a drink by immersing the device into the drink. A method for constructing the device using polypropylene (PP) membrane sheet and an adsorbent.

This invention relates generally to zeolites and polymer compositions with zeolites having enhanced adsorption capacity for adsorption of water, ammonia and other similar compounds. The invention is directed particularly to aluminosilicate zeolites, and methods for preparing zeolite entrained polymer compositions having enhanced water adsorption properties. This invention relates also to improved packaging materials with enhanced water adsorption properties incorporating the polymer compositions containing zeolites.

An insulation material is disposed in the cavity. A getter assembly is disposed in the cavity and includes a primary getter material that is deposited on a plate. A cover layer is deposited over the primary getter material on the plate. A vessel is nested within the primary getter material. A secondary getter material is disposed within the vessel. A protective enclosure is disposed around the getter assembly.

A filtering and adsorbent sampling and enrichment system comprising a stationary phase consisting of a felt of activated carbon fibres with a micro-meso porous conformation and specific surface area of about 1500 m2/g and sampling and/or enrichment standards, confined within a closed casing, is described, as well as the method for obtaining it and the relative process for the analysis of organic and inorganic analytes that uses said system.

An object is to provide a new form of adsorbent suitable for a high performance canister. An adsorbent including activated carbon is used as the adsorbent for the canister and satisfies the following conditions. P.sub.0.2/100 expressed by Equation 1:

P.sub.0.2/100=X÷Y×100  (Equation 1)

is 18% or more, in Equation 1, X represents an amount of adsorbed n-butane gas per 100 parts by weight of the adsorbent at 25° C. under an atmosphere where a gas pressure of n-butane gas is 0.2 kPa, and Y represents an amount of adsorbed n-butane gas per 100 parts by weight of the adsorbent at 25° C. under an atmosphere where a gas pressure of n-butane gas is 100 kPa.
