| Abstract: | The experiment of detecting volatile phenol in water by 4-aminoantipyrine spectrophotometry and iodine as oxidizer showed that the limit of detection was 1 ug/L, and the linear range was 2.0 -24.0 ug/L, r =0.9995. After the experiment factors were optimized, the precision of the method was 3.5% , and the recoveries of standard addition was 96.3% - 106%. The precision and accuracy of experiment meet the requirement. |
