Review of ion imprinted polymers nanofiber with technology electrospinning: An advanced materials for removal of heavy metal ions

Abstract

The existence of essential heavy metal ions that pollute the environment has become a substantial concern for countries worldwide due to their ability to damage ecosystems and harm living things. Therefore, research in the field of materials science to eliminate the presence of heavy metal ions that pollute the environment, such as Fe (III), Pb (II), Ni (II), Hg (II), Cd (II), Cr (VI), Ru (III), and As (III) need to be developed. Ion Imprinted polymers nanofiber (IIPs-NF) is one of the advanced materials with the ability to determine and remove heavy metal ions containing a high degree of selectivity and stability. The use of conjugate electrospinning technology in producing nanofiber (NF) can expand the surface of the material and the recognition sites for target ion elements. This research is a literature review of scientific articles on the development of ion imprinted polymers (IIPs) intelligent NF materials that utilize electrospinning technology. It discusses initial research in the preparation of IIPs samples, the principles of the synthesis method, the characterization analysis that needs to be conducted and the adsorption research of the IIPs-NF adsorption applications. The results showed that modification of the IIPs material with electrospun conjugation can increase the adsorption capacity and have several advantages such as high stability, biocompatibility and a better regeneration. Therefore, this material has great potential to become an advanced device that plays a role in overcoming harmful metal ions.
