FIELD: chemistry.
SUBSTANCE: this invention refers to production and application of sorbents. Offered is preparation method of composition for phosphate adsorption, including the stages as follows: a) base addition to aqueous solution containing ferric (III) sulphate and/or nitrate salt solution to deposit ferric hydroxide, b) optional water flush of produced deposit to produce aqueous suspension of ferric hydroxide, c) addition to produced aqueous suspension of component inhibiting deposit ageing ferric hydroxide produced in the stage b), d) drying of composition produced at the stage.
EFFECT: production of phosphate adsorbent with lowered chlorine content of for oral and parenteral preparations for human or animals.
