The development and use of 'green' electrode materials is extremely attractive for the routine use of disposable metal sensors. Bismuth is an environmentally-friendly element and a bismuth film electrode was proposed as an alternative to mercury film electrodes. Compared with bismuth, stannum is a more 'environmentally friendly' material. The stannum-bismuth composite film electrode prepared by the in situ electrodeposition of stannum and bismuth on the glassy carbon substrate is reported for the first time. Compared with bismuth film and stannum film electrodes, the stannum-bismuth composite film electrode revealed better electroanalytical performance, and can be used as a possible alternative electrode for electrochemical stripping analysis of trace heavy metals.
对于一次性金属传感器的常规使用而言,开发和使用“绿色”电极材料极具吸引力。铋是一种环保元素,铋膜电极被提议作为汞膜电极的替代品。与铋相比,锡是一种更“环保”的材料。通过在玻碳基底上原位电沉积锡和铋,首次制备了锡铋复合膜电极。与铋膜和锡膜电极相比,锡铋复合膜电极表现出更好的电化学分析性能,可作为电化学溶出分析痕量重金属的一种潜在替代电极。
