| Abstract: | A grand-lot fast determination of permanganate index in environmental water samples was conducted using continuous flow analysis. Its results had excellent accuracy and reproducibility with a detection limit of 0.16 mg/L; the relative error of analyzing the certified reference materials were -5.4%, -4.1% and 1.6%; parallel determination of RSD were 0.45% ～ 3.1%; recoveries of spiked samples were 90.1%～97.1%. The relative error were -2.8%～2.7% between the result of the actual water sample and that of the standard method GBl1892-1989. |
