| Abstract: | In NH3-NH4Cl buffer solution of pH9.8 phenol can reacts with 4-aminoantipyrine and potassium ferricyanide to form a red substance. The red substance can be extracted by C18 column and eluted by ethanol, then can be determined by spectrophotometry at 470 nm. The range of determination was 0.05-1.20 mg/L. The method has been applied to the determination of phenol in waster waters with satisfactory results. |
