| Abstract: | Total phosphate in water was determined by using on-line digestion flow injection analysis method using automated flow injection analyzer developed by Titan Intruments.The detection limit was 0.008mg/L P and the liner range was 0.1-5mg/L P(r=0.9998).The relative standard deviation was 0.69% and the recovery was 93%-111%.The method is rapid,simple,sensitive,the linear range,precision and accuracy all consist with GB standard. |
