Abstract
A new method was developed for the determination of aniline in waste w ater. Aniline fan react with sodium nitrite in thr acid medium. Its di azonium products can react continually with sodium sulfite and formald ehyde. The last reaction products can reduce et the mercury electrode with a sensitive adsorptive wave (E(p) = -0.72 V, vs. SCE). The concen tration of aniline is linear with peak current in the range of 1.00 x 10(-7)similar to 5.00 x 10(-4) mol/L. The detection limit is 5.00 x 10 (-8) mol/L. The behaviour of polarographic wave was studied and the me chanism oi electrode reaction was explored.
