| Abstract: | The polysiloxane elastomer, which could be used as heavy metal ion adsorption material, was successfully synthesized with HS-P(EO/PO)-SH and PVMS-b-PDMS as starting materials by thiol-ene click chemistry. The structure of the polysiloxane elastomer was characterized by FT-IR and 1H NMR. The thermodynamic properties of the polysiloxane elastomer and the adsorption of heavy metal ions in solution were studied. The results showed that the elastomer had excellent thermal stability, and had a good adsorption ability to nickel ions at room temperature. It could be used as a kind of heavy metal ion adsorption material with excellent properties. |
