Mercury(II) ions are emerging as a result of more human activity, especially coal-fired power plants, industrial processes, waste incineration plants, and mining. The mercury found in different forms after spreading around diffuses the nature of other living things. Although the damage to health is not yet clear, it is obvious that it is the cause of many diseases. This work detects the problem of mercury(II) ions, one of the active pollutants in wastewater. For this purpose, it is possible to detect the smallest amount of mercury(II) ions by means of the mercury(II) ions suppressed quartz crystal microbalance nanosensor developed. Zinc(II) and cadmium(II) ions are chosen as competitor elements. Developed nanosensor technology is known as the ideal method in the laboratory environment to detect mercury(II) ions from wastewater because of its low cost and precise result orientation. The range of linearity and the limit of detection are measured as 0.25 × 10-50 × 10 m. The detection limit is found to be 0.21 × 10 m. The mercury(II) ions imprinted nanosensors prepared according to the obtained experimental findings show high selectivity and sensitivity to detect mercury(II) ions from wastewater.
汞（II）离子因更多的人类活动而出现，尤其是燃煤发电厂、工业生产过程、垃圾焚烧厂和采矿活动。汞在扩散后以不同形式存在，会影响其他生物的特性。尽管对健康的损害尚不清楚，但显然它是许多疾病的成因。这项工作检测了废水中活性污染物之一汞（II）离子的问题。为此，借助所开发的抑制汞（II）离子的石英晶体微天平纳米传感器，能够检测出最少量的汞（II）离子。选择锌（II）离子和镉（II）离子作为竞争元素。所开发的纳米传感器技术因其低成本和精确的结果导向，在实验室环境中被认为是检测废水中汞（II）离子的理想方法。线性范围和检测限分别测定为0.25×10⁻⁵ 至 50×10⁻⁵ 摩尔，检测限为0.21×10⁻⁵ 摩尔。根据所得实验结果制备的汞（II）离子印迹纳米传感器对检测废水中的汞（II）离子表现出高选择性和高灵敏度。
