Abstract

Polyvinyl alcohol or a cellulose material, e.g. cotton gauze, regenerated cellulose, powdered alpha-cellulose or methyl cellulose, is treated with an aqueous solution of a water-soluble salt of a metal, at a temperature and for a period of time sufficient to form a solid alcoholate of the metal. A catalyst, such as an aqueous solution of a salt of a metal more basic that the metal whose alcoholate is to be formed, particularly an alkali metal, may also be present. Specified metals are silver, gold, platinum, antimony, cadmium, chromium, iron, magnesium, manganese, titanium, zinc, zirconium and cerium. The alcohol may be treated first with an acid to form an ester, e.g. with formic or phosphoric acid. The treatment may take place in several stages, each employing a salt of a less electropositive metal than the preceding one. The product may be used as an antiseptic agent, as a carrier for orally administered iron in anaemia treatment, as an antiseptic bandage, as a separator for an electric battery, and for decontaminating polluted liquids.ALSO:Polluted liquid is decontaminated by bringing it into contact with a solid oligodynamic metal salt of an organic polymeric material which originally contained at least one hydroxy group, e.g. cellulose derivatives, and polyvinyl alcohol. In an example, powdered dry silver cellulosate is placed in a bag of cotton fibres (which itself may have its silver salt present) and immersed in a body of polluted water.ALSO:Cotton gauze is steeped in an aqueous solution of 1 per cent silver nitrate containing 0,7 per cent sodium acetate for thirty minutes at 80 DEG C. and the gauze washed and dried to become a self-sterilized antiseptic bandage.
