In this paper, duck feather fiber was treated by alkaline solution first, then its Cu2+ sorption capacity was tested and the sorption mechanism was studied by utilizing infrared spectrum (FTIR) and wide-angle X-ray diffraction (XRD). Moreover, desorption properties of the treated duck feather fiber were investigated in order to exploit it as a recycled industrial effluent treatment material. At last, duck feather fiber was air-laid and thermal-bonded into a kind of composite nonwoven fabric by adding bicomponent low melt PE/PP fiber as binder fiber. It is found that duck feather/bicomponent PE/PP fiber composite nonwoven fabrics show good mechanical properties and Cu2+ and Cr6+ sorption capacity. It is a promising material for textile dying effluent treatment.
In this paper, feather was used to adsorb lead ions as a new type of adsorbent materials. For recycling feather, NaOH solutions as the desorption solutions were adopted to desorb feather after adsorption of lead ions, and then the factors which affect the desorption effect, such as desorption time, concentration of desorption solutions, temperature and so on were studied. It was found that the optimum desorption conditions are: the desorption time of 60min, the concentration of NaOH solutions of 30mmol/L, the temperature of 40°C.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
