FI-Chemiluminescence Determination of Phenol in Waste Water

A study on the chemiluminescence behavior of the reaction system of KMnO4,H2O2 and phenol was made by the FIA technique,and various factors affecting the magnitude of intensity of chemiluminescence were tested and discussed.Based the experimental results,a new method for determination of phenol was proposed.Detection limit of the method was found to be 3×10-5g·L-1.Linear relationship between the values of peak height and concentration of phenol was obtained in the range of 1.0×10-4-1.0×10-1g·L-1.Precision of determination was tested at the concentration level of 4.0×10-4g·L-1 of phenol and value of RSD′s (n=11) found was 1.6%.This method has been used in the determination of phenol in samples of waste water,giving results in consistency with the results of the photometric method.
