| Abstract: | A polarography analysis method was reported for analyzing phenylamine in field samples. The phenylamine was transformed into phenylhydrazone through a serial of reactions. The phenylhydrazone got a sensitive seeondary derivative polarographic wave which ranged of linearity 8.0 ×10^-7～5.0×10^-4mol/L. The method was applied successfully to the analysis of wastewater and air. |
