Gel of Ammonium phosphomolybdate, procedure for removing Cesium from aqueous solutions using the method of obtaining Said gel and

摘要

The Invention relates to a gel of Ammonium phosphomolybdate, novel for his State in the form of Gel Porous, quasi esfu00e9ricasy mainly forms for use in the absorption of Cesium.Another aspect of the invention consists of a Method by dichogel 1990 Cesium from Aqueous Solutions of Ammonium phosphomolybdate,It comprises the steps of Carrying the PH of an aqueous solution to a value less than or equal to 1.5; the setting in contact with a solution of ammonium fosfomolibdatode gel gel / Solution ratio equal to or less than 1 / 200 and a time of upheaval.Also proponeun method for obtaining Said gel which comprises the steps of Mixing of Ammonium molybdate, Phosphoric Acid, nitric acid and Water.Deesp esadoutilizando hydroxymethyl Cellulose, obtained by gelation of sol dripped on a bath of nitric acid - ammonium nitrate and soft Wash.The Invention elcompuesto, through its State in gel form, allows to obtain a mayoreficien CLA in the removal of Cesium from Aqueous Solutions.An application of the invention is used in the removal of Cesium in nuclear waste.
