Determination of Phenol Using Kinetic Spectrophotometric Method by Methyl Orange as a Indicator

JI Ning-ning

Abstract

The method is based on the inhibitory effect of phenol on the reaction between bromate and methyl orange in acidic media at 80 ℃.Phenol could be determined in the concentration range of(0.40) μg·mL~(-1)~2.8 μg·mL~(-1),the detection limit is 0.1777 μg·mL~(-1).The relative standard deviation for eleven replicate determination of 1.0 μg·mL~(-1) phenol was 1.44%.
