A core-shell amidoxime electrospun nanofiber affinity membrane for rapid recovery Au(Ⅲ)from water
文献摘要：
An affinity membrane was prepared by coaxial electrospinning and amidoxime(AONFA),and it was applied to selectively recovery Au(Ⅲ)from an aqueous solution.The static adsorption results showed that,when pH at 5,the maximum adsorption capacity of AONFA membrane for Au(Ⅲ)was 509.3 mg·g-1.AONFA membrane exhibit much higher affinity and selectivity towards Au(Ⅲ)than other metal cations.The membrane could be regenerated effectively by mixture solution of thiourea and HCl,and the desorp-tion ratio reached almost 100％after 4 hours desorption.The dead-end filtration results showed that,the membrane utilization efficiency and adsorption capacity can be improved by increasing the flow rate,while increasing the concentration shorted the breakthrough process and had little impact to adsorption capacity.We can flexibly adjust the flow rate and concentration according to the situation to obtain the maximum utilization efficiency of the membrane in filtration process.The dynamic adsorption capacity is higher than the static adsorption capacity.The adsorption mechanism for Au(Ⅲ)is electrostatic adsorp-tion and reduction.Thus,AONFA membrane filtration was demonstrated to be a promising method for continuous recover Au(Ⅲ)from wastewater.
