Ultraviolet Spectroscopy Applied to Simultaneous Determination of NO3--N and NO2--N
A new method to optimize parameters has been built for BP network following uniform design. The ultraviolet absorbed spectroscopy of NO3-1 and NO2-1 was studied. On the basis of back propagation algorithm, neural networks were applied to deal with the spectroscopy data.A new method to determine NO3--N and NO2--N in water samples was proposed. Good results were obtained.
