Abstract
Disclosed is a method for making absorbent for metal. In the method, at first, solution of first monomer and solution of second monomer are provided. Then, the solution of the second monomer is introduced into the solution of the first monomer. Finally, a microwave reaction is executed to provide micro-alls of absorbent for metal.
Claims12
A method for making an absorbent for metal including the steps of:
- providing a composition of a first monomer and a composition of a second monomer;
- wherein the composition of the first monomer includes the first monomer and a solvent;
- wherein the composition of the second monomer includes the second monomer, an initiator and a cationic dispersant;
