摘　　要：采用Na2S2O5对羽毛进行改性来提高羽毛对Pb2+的吸附能力。研究了Na2S2O5溶液浓度与改性羽毛对Pb2+吸附能力之间的关系,分析了改性前后羽毛的结构变化,同时研究了NaOH和Na2S溶液对吸附了Pb2+羽毛的解吸附效果。通过熔喷技术将羽毛成形为羽毛/聚丙烯(PP)熔喷滤芯,并采用自建的滤芯动态吸附装置评价了滤芯对Pb2+的动态吸附效果。研究表明:Na2S2O5是一种能有效提高羽毛Pb2+吸附性能的改性方法;改性羽毛/PP滤芯比羽毛/PP滤芯和纯PP滤芯表现出更好的Pb2+动态吸附能力,是一种值得深入研究和开发的重金属废水过滤和吸附材料。Na2 S2 O5 solution was used to modify feather fiber in order to increase its adsorption ability of Pb 2+.The relationship between the concentration of Na 2 S2 O5 solution and the adsorption capacity of Pb 2+of was studied .The structure changes of feather fiber before and after modification were investigated .At the same time, the desorption effects of NaOH and Na 2 S solutions on the feather fiber absorbed with Pb 2+were studied as well .Finally, feather fiber was prepared into feather fiber/polypropylene melt-blown filter cartridge and their dynamic absorption properties of Pb 2+were investigated by using the equipment set up in our lab.The study demonstrated that Na2S2O5 solution could enhance adsorption capacity of Pb2+of modified feather fiber effectively .The modified feather fiber/PP filter core on dynamic absorption properties of Pb 2+was better than that of feather fiber/PP filter core or PP filter core .The method could be studied on application of metal waste water filtration and absorption .
