Abstract

The development of new low-cost, highly selective and efficient methods for the separation and detection of heavy metal ions in aqueous environments is of great importance for water safety and biological health. In this study, a novel ion separation membrane was prepared for the separation of copper ions in cadmium ion detection solution. Compared with the commercial membrane, the ion mobility was increased by 64.02 %, and further separated by selective complexation of thiacalix[4]arene-p-tetrasulfonate (TCAS), and the separation factor for Cu/Cd reached 34.66. This allowed Cd to be detected preferentially, and reduced the interference of other ions in the detection. The joint electric field environment was regulated to separate the organics and reduce the interference to the detection. The sensing performance was enhanced by modifying the screen-printed electrodes. The proposed sensing platform allows for simultaneous pre-processing and detection and has a detection limit of 0.19 μg-L⁻¹ (S/N = 3) for Cd²⁺.

期刊介绍： The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field. Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
