Abstract： |
The invention discloses a preparation method of poly-antimonic acid ion exchanger. The method of the invention includes the following steps: 1) antimony trioxide oxidation: antimony trioxide is oxygenated under the presence of oxidants and prepares hydrated antimony pentoxide sol; 2) Oxide aging: aging the prepared hydrated antimony pentoxide sol 1- 30 days under constant temperature of 0 ~ 70 degreeC; 3) drying and exploring in order to form particles: drying the aged hydrated antimony pentoxide sol to poly-antimonic acid solid, putting it into thin nitric acid solution to explore particles and prepares poly-antimonic acid ion exchanger. The invention method has the following advantages: 1. mild preparation conditions and short reaction time; 2. simple installations, low requirements to equipment and easy operation process; 3. preparation process avoids the touch of toxic chemicals; 4. low-cost preparation process, less art operating cost and good adsorption properties of ion exchanger; 5. high selective adsorption capacity of the prepared poly-antimonic acid inorganic ion exchanger to Sr2+. |
