Study on the Method of Determining Volatile Phenols in Water by Flow Injection Method
Flow injection analysis was used to detect volatile phenols in water,and the correlation coefficient r＞0.999 9 was obtained within the linear range of 0～100 μg/L.The detection limit was 0.24 μg/L,the precision was＜2％,and the recovery rate was between 95％and 105％.By using the Grubbs method,F-test,and t-test in significance testing to compare and analyze data with the traditional 4-aminoantipyrine spectrophotometric method,and discussing the influencing factors in actual detection,it is shown that this method has higher sensitivity,reproducibility,and accuracy.
