Problems solved by technology

[0002] The detection of inorganic elements, especially heavy metals, is one of the testing items faced by many scientific research units or testing institutions in the environmental field, especially the content of heavy metals in groundwater, surface water, seawater and other issues related to drinking water in daily life. Therefore, The detection of inorganic elements and metal elements is one of the must-test items for scientific research units or testing institutions in the environmental field. Traditional detection methods include microwave digestion, strong acid and strong alkali, distillation, rotary evaporation, etc. After treatment, atomic absorption spectrometer, atomic fluorescence Spectrometer, plasma emission spectrometer, plasma mass spectrometer and other instruments are used for analysis. These methods take more than half an hour, the steps are cumbersome, the operation is complicated, time-consuming and laborious. Therefore, a faster and more accurate pre-treatment method is invented. method and detection method, it is very necessary
