چکیده انگلیسی
A novel flow injection procedure was developed for the determination of p-aminophenol (PAP) based on the inhibition by PAP of the chemiluminescence from luminol-dimethylsulfoxide (DMSO)-NaOH-EDTA system. The method has merits of higher sensitivity, wider linear range, simpler procedure, and a more rapid analyzing speed. It is applicable for the determination of PAP in the range of 2.5Ã10â10-5.0Ã10â8 g mLâ1 with a detection limit of 1.9Ã10â10 g mLâ1. The relative standard deviation (RSD) for 5.0Ã10â9 g mLâ1 PAP is 0.78% (n=15). The method has been successfully used to determine PAP in industrial wastewaters and environmental waters. Additionally, the inhibition mechanism was also discussed briefly.
