Synthesis of graphene oxide/ polyvinyl alcohol (GO/PVA) composite film as an adsorbent

Thu Le Dieu, Hoang Tran Vinh

Abstract


In this study, heavy metal ions or organic in the aqueous solution are removed by adsorbent without filtration or centrifugation as well as incorporate magnetic materials into the adsorbent. A composite film GO/PVA from PVA and self – synthesized GO by co - precipitation method has synthesized successfully. This composite was characterized by XRD, SEM, FT-IR to evaluate the properties of this material. The results showed that there was an interaction between GO and PVA so we have tested the adsorption capacity of this composite with Co(II) ions and the obtained efficiency of this process was 99.5% with the initial concentration of solution is 20 mg.L-1. This film is completely capable of removing heavy metal ions from waste water.
