Abstract

When determining aniline and nitrobenzene using colorimetry, the existence of aniline may disturb the determination of nitrobenzene. Using interference curve removal method can quantitative illustrated the disturbance of aniline to get the real content of nitrobenzene. Using this method to determine aniline, the standard deviation was 0.29 μg, the relative standard deviation was 1.9%, recovery rate was 97%. To determine nitrobenzene, the standard deviation was 057 μg, the relative standard deviation was 56%, recovery rate was 95%.
