Abstract

Composite adsorbent precipitates suitable for the treatment of liquids such as sugar solutions and of gases are prepared by precipitating an alkaline earth salt and depositing upon it another alkaline earth salt, under such conditions as to produce precipitates having adsorbent properties, the precipitation being preferably effected above 80 DEG C. A precipitate of calcium carbonate may be prepared and a coating of dicalcium phosphate produced upon it by adding a small quantity of phosphoric acid. If the precipitate is to be dried, substances may be admixed with it to prevent the particles agglomerating. Such substances may be tannin, starch, glue, or soda, or, when it is to be used for the treatment of sugar solutions, sugar may be used as the addition. A relatively expensive precipitate such as calcium phosphate, citrate, tartrate, oxalate or sulphite may be precipitated upon a relatively cheap precipitate such as calcium carbonate. Specifications 183,485 and 184,473, [both in Class 46, Filtering &c.], and 222,159 are referred to.
