水污染动态实时监测的便携式电子舌分析仪

The Portable eTongue for Real Time Water Pollution Detection

论述了新型用于水污染动态实时监测的电子舌分析仪器。该仪器采用离子选择性传感器检测技术、电化学溶出伏安检测技术和光寻址电位传感器检测技术,结合计算机快速检测技术,可以同时快速检测工业和生活污水中多种重金属离子的浓度。在硬件设计上以最小系统为核心,具有配置灵活、可扩展性好等特点。在软件设计上,分模块化实现,包括数据通信、数据预处理、数据存储和控制等模块,方便移植。实验结果表明,本仪器具有良好的定量检测能力。

The portable eTongue for real time water pollution detection was introduced. The instrument consists of three methods, including ion selective electrode, the electrochemical stripping voltammetry and light-addressable potentiometric sensor. Integrated with computer analysis technology, the eTongue was able to detect several trace metals in water pollution. The hardware design is based on a core system, which features flexible configuration and wonderful extensibility. The software system was consisted of several modules including data communication, data processing, data storage and process control etc. Each of the modules could be compiled indepedently while the others were not affected. The experiment results show that the eTongue has good ability of quantitative detection for heavy metal.
