Abstract:
1. A method for preparing a magnetic polymer, comprising: a) putting a polymer in a container, the polymer having groups capable of absorbing Fe b) adding a Fe c) washing the resultant polymer of b) to eliminate unabsorbed Fe d) adding a divalent metal salt solution into the polymer of c), and stirring to make the polymer absorb divalent metal ions; e) washing the resultant polymer of d) to eliminate the unabsorbed divalent metal ions; and f) introducing an inert gas, adding an alkaline solution to control the pH value in a range from 9 to 14, stirring and heating for a period of time sufficient to produce a magnetic polymer, wherein a method for preparing a magnetic polymer is afforded.
