ZIF-8@PVA-CD composite adsorbent material and fabrication method for treating growth regulators in water.

Abstract

The invention relates to a ZIF-8@PVA-CD composite adsorbent material in the form of cubic particles with a porous structure and a method for fabricating this material. The material is formed from a ZIF-8 metal-organic framework dispersed in a PVA-CD biopolymer matrix through a two-stage process: (1) Attaching Zn2+ metal centers on the PVA-CD polymer matrix and (2) Growing ZIF-8 crystals on the PVA-CD polymer matrix to fabricate ZIF-8@PVA-CD composite particles. The product has a size of 1-5 mm, is easily recovered, has good mechanical strength and is highly effective in treating 6-Benzylaminopurine (6-BAP) in aqueous environments.
