摘要

Abstract

Using cobalt-containing wastewater as cobalt source

Zeolitic imidazole frameworks-67/Graphene(ZIF-67/Graphene) composites were prepared by in-situ synthesis method in this paper. The adsorption properties of Phosphate Anion (PO

) on the composite were compared with that of Graphene. The effects of reaction time

temperature and dosage on the adsorption capacity of PO

on these materials as well as the reusability of the material were discussed. The structure of these materials and the removal mechanism of PO

on the composite material were analyzed by Scanning electron microscopy(SEM)

Fourier transform infrared spectroscopy(FTIR)

X-ray diffraction(XRD) and nitrogen adsorption-desorption analysis. The results show that the adsorption capacity of PO

by ZIF-67/Graphene is the maximum

which can reach 118.95 mg/g. The adsorption mechanism of PO

is based on ion exchange

electrostatic attraction and π-π interaction. The material has good recycling ability.
