| Abstract: | In this paper, the performance test method of polarograph is studied in detail, and the best conditions of the performance test about the polarohraph is put forward. The polarographic condition: intial potential is -0.40 V; final potential is -0.90 V; scanning speed is 250 mV/s; three potentials; working electrode is dropping mercury electrode; second derivative wave. In order to increase the signal-to-noise ratio we choise high sensitivity position. Mesuremrent : add the detectability test solution tothe electrolytic cell, nitrogen remove oxygen 5 min, measure; add the blank solution to the electrolytic cell, nitrogen remove oxygen 5 min, measure. |
