A search for a sorbent capable of simultaneously extracting both phosphate anions and ammonium cations from highly competitive medium like the biological environment human's body was realized.For this purpose comparative study sorption ions aquatic environments in absence any backgrounds electrolytes Ringer's solution by activated charcoal, its oxidized forms mineral amorphous sorbents -powdered titanium silicate, as well spherically granular hydrous zirconium silicate dioxide, obtained original methods synthesis, some their ion-substituted comparison with commercially available silica gel carried out.The features studied are discussed.It established that properties depend strongly chemical nature.It determines selectivity ion-exchange possibility chemosorption processes solution.A relationship between calcium supposed which made it possible to assume mechanism.Based on mechanism understanding respect were considerable improved converting initial sample into Ca-and Ce-ion-substituted without significant loss high toward cations.
