    • Rapid detection of arsenic, antimony, bismuth and mercury compounds

      Time of Update: 2022-03-17
      Figure 4-1 Test results of arsenic, antimony, bismuth, and mercury compounds[Result judgment]If the surface of the copper sheet changes color after heating for 30 minutes, the possible compounds in the sample can be inferred according to Table 4-1, and the sample should be retained and confirmed separately if possible . Table 4-1 Judgment of the detection results of arsenic, antimony, bismuth, and mercury compounds   
    • Atomic fluorescence method of solid waste mercury, arsenic, selenium, bismuth and antimony (1)

      Time of Update: 2022-02-27
      (2) Method principleAfter microwave digestion of solid waste and leachate samples, they enter the atomic fluorescence spectrometer. This solution was prepared on the same day for the determination of arsenic, selenium, antimony, and bismuth .
    • Soil and sediment mercury, arsenic, selenium, bismuth, and antimony atomic fluorescence method (1)

      Time of Update: 2022-02-27
      (1) Scope of applicationMicrowave digestion/atomic fluorescence method is suitable for determining the content of mercury, arsenic, selenium, bismuth and antimony in soil and sediment . (2) Method principleAfter the sample is digested by microwave, the test solution enters the atomic fluorescence photometer.
