| Abstract: | Iron content in natural water was determined by a self-assembled flow injection analysis system with double beam spectrophotometer as detector. The optimum analytical conditions were studied. The analytical performance of single beam spectrophotometer and double beam spectrophotometer was compared. The results show that the two methods has same analytical performance, but the double beam spectrophotometer has higher sensitivity. |
