Scope

Main technical content: The portable heavy metal element water quality analyzer applicable to this standard has the following outstanding advantages: it can operate under atmospheric pressure conditions without requiring special gases, has low operating costs, is compact in size, and can perform real-time online analysis of heavy metals in water bodies and simultaneous analysis of multiple elements. It can be applied to the monitoring of wastewater discharge from chemical enterprises and emergency monitoring of sudden water pollution incidents, and has a very broad market prospect. The portable high-throughput metal ion water quality analyzer based on atmospheric pressure electrolyte glow discharge technology uses liquid cathode glow discharge technology, which is a type of micro-plasma technology. The basic principle of metal ion determination is: under normal pressure, with the solution as one electrode and tungsten or titanium electrodes as the anode, high voltage is applied to the two electrodes, resulting in gas discharge between the electrodes. During the discharge process, the solution in the liquid electrode is continuously vaporized, causing the metal ions dissolved in the solution to enter the plasma and be excited, producing an emission spectrum. The intensity of the emission lines in the spectrum is closely related to the solute components in the solution, so the detection of metal ions in the solution can be achieved through the detection of the emission spectrum. The portable heavy metal element water quality analyzer applicable to this standard is a commercial instrument based on this principle. At present, the instrument has been applied to on-site water quality analysis of heavy metal ions in the field, meeting the analysis requirements. The formulation of this standard will provide a more innovative and efficient choice for environmental detection and promote the comprehensive improvement of environmental protection work.
