| Abstract: | A flow injection analysis (FIA) with resin preconcentration for spectrophotometric determination of trace phenols in water with 4-aminoantipyrine (4-AAP) was described. When sampling frequency was 24 samples/h, the detection limit was 0.05mg/l for phenol, the linear range of calibration graphs was 0.05-7mg/l, the relative standard deviation (n= 10) was less than 2%, and the recovery rate was 99-105%. |
