Abstract: Taking advantage of the large number of oxygen-containing functional groups on the surface of polyvinyl alcohol (PVA),we successfully connected it with polyethyleneimine (PEI) polymer through a series of chemical modifications to obtain PEI-PVA nanospheres.The morphology and chemical compositions of the nanospheres were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy.The results of batch experiments showed that PEI-PVA nanospheres had excellent adsorption effects for anionic surfactant wastewater under both acidic and alkaline conditions,and the adsorption capacity increased with the extension of the treatment time and tended to be stable after about 24h.The polymer film prepared from PEI-PVA nanospheres had great adsorption treatment effect and strong reusability,which had broad application prospects.
