| Abstract: | It is reported in this paper that the method of artificial neural network based on the back-propagation network is applied to the simultaneous UV-spectrophotometric determination of NO~-_3 and NO_2 nitrogen in water samples. The proposed method has been checked with standard water samples and satisfactory results were obtained. It is also proved that the experimental system designed by using the uniform design is quite satisfactory. |
