PANI-SnP复合膜电极在镍镉废水中的电控离子交换性能
Electrochemically Switched Ion Exchange Properties of PANI-SnP Composite Films in Wastewater Containing Ni2+ and Cd2+
摘要
Abstract
Electroactive PANI-SnP composite films were prepared by drop-coating method on Pt electrodes and investigated as electrochemically switched ion exchange (ESIX) materials for the separation of Cd2+ from aqueous solutions.The composition and morphology of the composite film were characterized by Fourier transform infrared spectrometer (FTIR) and scanning electron microscope (SEM).In solutions containing 0.1 mol· L-1 Ni(NO3)2 and Cd(NO3)2,cyclic voltammetry (CV) and electrochemical quartz crystal microbalance (EQCM) were used to investigate the electrochemical behavior and ion-exchange mechanism of PANI-SnP composite film.The elementary composition of PANI-SnP composite films in both oxidation and reduction states were also characterized by energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS).Experimental results show that the PANI-SnP composite films have reversible electrochemical behavior in aqueous solutions containing Cd2+ and Ni2+,respectively.The PANI-SnP composite film electrodes displayed a high selectivity toward Cd2+ in Cd2+/Ni2+ binary mixtures and the Cd2+ ions could be separated effectively from aqueous solutions by ESIX processes.关键词
