Abstract:
      A new type of chromatographic stationary phase for detecting anion with suppressed conductivity detection was prepared. Under the optimal chromatographic conditions, a variety of phosphorus-containing anions were successfully determined using the home-made chromatographic stationary phase. Using KOH as eluent, phosphate, pyrophosphate, trimetaphosphate, and tripolyphosphate were separated and analyzed. The results show that the method has good linearity with standard addition recovery of 90%~106%. And the results for real samples were satisfied.
