1. a kind of hypersensitive sulfate radical nephelometric analysis method, it is characterised in that comprise the following steps:

  • 1) using ultra-pure water as sample current-carrying, ultra-pure water is delivered to sampling valve (4) by pump (3), by sulfate radical sample to be detectedProduct inject sampling valve (4), and sulfate sample to be detected is delivered in threeway blender (6) through sample current-carrying;

    2) while the glycerin-ethanol that will be acidified through hydrochloric acid-barium chloride solution system is delivered to by pump (3) or another pumpOn-line mixing is carried out in threeway blender (6) in threeway blender (6) and with sulfate sample to be detected, is flowed through after mixingReaction ring (7) reaction, generates barium sulfate emulsion;

    3) by step

         2) the barium sulfate emulsion of generation first flows through optical fiber (8), the influent again being connected with light emitting diode (10)In core waveguide (9), then flow through photodiode (11) after enter waste liquid pool (14), it is finally right using photodiode (11)Light intensity change when barium sulfate emulsion flows through liquid core waveguide pipe (9) is detected.
