This activity explores an alternative use of a superabsorbent polymer known as a water absorbing material. A dilute solution of CuCl[subscript 2] is treated with a small piece of unused disposable diaper containing superabsorbent sodium polyacrylates. The polymer is used for the removal of Cu[superscript 2+] ions from the solution. The Cu[superscript 2+] ions in the solution are sequestered through ion exchange with the sodium ions of the insoluble polymer. The solution loses its color, and the polymer gels turn blue. The Cu[superscript 2+] solutions before and after the treatment are further tested with soap solution to confirm the action of the polymer. (Contains 2 figures and 1 scheme.)
