at considerable speed
1.In chemical structure of chloramphenicol contains considerable elec-tronegativity of chlorine, by using ethanol-water(1:1) solution,there was-a very good of secondary derivative high-speed pulse polarogram peak at -0.06V(vs Ag/AgCl) The linear relationship between concentration and secondary derivative high-speed pulse polarogram peak height was obtiained in the concentration range of 1.0~6.0×10-4 mol/L.
