| titleOfInvention | Improvements relating to the production of cation-exchange materials |
| abstract | A cation-exchange material is prepared by treating a material having exchangeable silver with barium hydroxide. A silver exchange material preferably made by treating a sodium aluminium silicate with silver nitrate, is treated with a solution of barium hydroxide, preferably in sufficient quantity to render the distribution of the precipitated silver oxide in the material substantially uniform. The resultant material, without being washed, may be dried at temperatures below 100 DEG C. until the moisture content is reduced to 7 per cent. or less, and may be used as such, or mixed with the untreated silver exchange material. The product may be mixed with a substance, e.g., fuller's earth and compressed into briquettes. The treatment of the silver exchange material with barium hydroxide may be effected by percolation or by passing the barium solution first upwards and then downwards through a column of the untreated material. Examples are given, and Specifications 576,969 and 576,971 are referred to, the latter in the Provisional Specification only. According to the Provisional Specification, the silver cation exchange material may, if desired, be dehydrated before it is treated with barium hydroxide.ALSO:Sea water and other saline liquids are rendered potable by treatment with cation-exchange materials having exchangeable silver and barium. The material may be mixed with fullers earth so that it disintegrates in use after briquetting. The cation-exchange material is prepared by treating a material having exchangeable silver with barium hydroxide (see Group III). Specifications 576,969 and 576,971 are referred to. |
