摘要

Abstract

A novel flocculant based on hybrid coal gangue-polyacrylamide (HCGPAM) has been prepared by using modified coal gangue and polyacrylamide. Factors related to the preparation such as reaction time

temperature

concentration of the polymer monomer and ratio of initiators are investigated. The product is characterized by infrared spectra (FTIR)

scanning electron microscopy (SEM)

X-ray diffraction (XRD)

aswell as viscometry. The flocculating tests on oilfield drilling wastewater show that the removal efficiency is 85.5% and the light transmittance is 53.6%. The results indicate that the coal gangue could be used for the preparation of inorganic-organic hybrid flocculant and the removal efficiency is much higher than that of commercial polyacrylamide (PAM) or PAM/ coal gangue blend.
