| Abstract | Electrochemical analytical challenge for cadmium(II) [Cd(II)] determination is to seek an efficient platform to realize the sensitive and selective detection. Herein, a sensing interface for the detection of Cd(II) was designed and constructed by the amination treated porous SnO2 nanowire bundles-room temperature ionic liquid nanocomposite (NH2/SnO2-RTIL). Through the delicate control of experimental conditions (deposition potential and electrolyte pH), the excellent sensitive and selective electroanalysis of ultra-trace Cd(II) was achieved using square wave anodic stripping voltammetry (SWASV). The NH2/SnO2-RTIL uses its efficient capture during the Cd(II) deposition step to enhance the sensitivity of the stripping response. Under the optimal experimental conditions, the NH2/SnO2-RTIL nanocomposite offered direct detection of Cd(II) within the desirable range (0.0267 mu M) in drinking water as specified by the World Health Organization (WHO), a limit of detection (3 sigma method) of 0.0054 mu M with a sensitivity of 124.03 +/- 3.75 mu A mu M-1 was obtained in the presence of common heavy metal ions. Finally, the analytical application of the proposed method toward the detection of Cd(1I) in a real water sample collected from Wangxiaoying sewage treatment plant, Hefei City, China, has been successfully verified.
