Cellulose fiber-containing structure

A deodorant fibrous material contains (1) as a first deodorant material, at least one deodorant component selected from inorganic type and polyorganic acid, ester or salt type components, (2) as a second deodorant material, at least one hydrazine compound and (3) a synthetic resin binder. The deodorant fibrous material can be produced by applying to a fibrous material by a padding or coating method, a liquid composition containing the above components (1)-(3), followed by subsequent heat treatment.

Deodorant fibrous material and method of producing the same

A deodorant fibrous material contains (1), as a first deodorant material, at least one deodorant component selected from inorganic type and polyorganic acid, ester or salt type components, (2), as a second deodorant material, at least one of a hydrazine compound and a specified polyvinyl amine compound and (3) a synthetic resin binder. The deodorant fibrous material can be produced by applying to a fibrous material, by a padding or coating method, a liquid composition containing the above components (1)-(3), followed by subsequent heat treatment.

The present invention relates to a method for purification of liquids. Fur particulars, the present invention relates to a method for purifying more precisely liquids in atomic power related fields, using a mixture of a polymer in which carboxyl groups are grafted onto a polyamide or a polyester as a cation exchanger and an anion exchanger.
