摘　　要：用极谱方法分析环境中的苯胺污染物的含量,苯胺重氮化反应产物再与亚硫酸钠、甲醛的反应物有一灵敏的二阶导数极谱波,峰电位-0.71V(vs、SCE)。研究了影响因素,优化了分析条件。线性范围在8.0×10-7～5.0×10-4mol/L,可用于废水与空气中微量苯胺的测定。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.
