Abstract
In this study, high surface area poly (lactic acid) (PLA)/tea polyphenols (TPs) porous composite nanofiber membranes (CNFMs) were prepared successfully by electrospinning and applied to adsorption of silver ions. The morphology and properties of the electrospun PLA/TPs CNFMs before and after adsorption of silver ions were investigated by scanning electron microscopy (SEM), energy dispersive spectrometer test (EDS), universal testing machine, etc. In addition, the adsorption capacities of PLA/TPs CNFMs for silver ions were determined by atomic absorption spectrophotometer. Adsorption tests showed that the electrospun PLA/TPs CNFMs exhibited good adsorption properties of silver ions, and the porous structure could promote the adsorption of silver ions.
