Abstract

It was found that poly(N-isopropylacrylamide) could be used as a transferring medium to effect the concentration of tris(1, 10-phenanthroline)iron(II) in homogeneous aqueous solution without using organic solvents at all. The optimum conditions, such as pH, poly(N-isopropylacrylamide) concentration, kind and concentration of counter anion, and the time for centrifugal phase separation were examined.
