Ultraviolet Spectroscopy Applied to Simultaneous Determination of NO3--N and NO2--N

    摘要
  • 摘要: 提出了用均匀设计法安排BP网络运行参数以进行优化的方法.研究了硝酸盐和亚硝酸盐在紫外区的吸收光谱.利用BP算法的人工神经网络处理光谱数据,提出关于同时测定水样中硝酸盐氮和亚硝酸盐氮的新方法.对实际水样进行了测定,结果满意.

     

    Abstract: 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.
