Spectrophotometric Determintion of Volatile Phenol in Refinery Waste Water by Flow Injection Analysis

An rapid method for determination of volatile phenol in refinery waste water was proposed,based on the combination of 4-amino-antipyrine coloring principle with flow injection technique.The analysis rate was 40 samples/h,and the linear range of the analysis 0.75~23.0μg/ml.The relative standard deviation(n=10) was 2.8% for phenol standard solution with the concentrtion of 1.50μg/ml.Comparing with conventional method,the determintion results for refinery samples were satisfactory,and it had no remarkable difference.
