Abstract

In the presence of potassium biphthalate-sodium hydroxide buffer solution at pH4.5,trace aniline in-hibitsstrongly the fading reaction of malachite green by oxidizing with potassium M28permanganate.Based on thisstudy,a novel inhibitory kinetic-spectrophotometric method hasbeen developed for the determination of trace aniline.The experimental resultsshow that the detection limit for aniline is0.38μg/L,the linear range of the determination is0.0~9.2μg/L,The method hasbeen applied to the determination of trace aniline in wastewater with satisfactory results.
