摘要：

A differential pulse polarographic method for the rapid and simple determination of tellurium by use of maximum wave has been studied. Differential pulse polarographic (DP) peak of tellurium (IV) in 1 mol dm** minus **3 phosphoric acid is observed in the potential range minus 0. 7- minus 1. 0 V vs. SCE. The peak current is very large in comparison with that in dc mode, or in normal pulse mode, being proportional to the concentration of tellurium-(VI) between 10** minus **8 and 10** minus **7 mol dm** minus **3 contents. The relative standard deviation for 3. 94 multiplied by 10** minus **8 mol dm** minus **3 tellurium (IV) under representative sets of good conditions was 0. 0342. The method has been applied to the determination of tellurium in carbon steel.
