人工神经网络流动注射分光光度法同时测定铜合金中的Fe2+和Ni2+
Simultaneous flow injection-spectrophotometer determination of iron and nick by artificial neural networks
【摘要】 用人工神经网络处理铜合金流动注射的吸收光谱数据,对Fe2+和Ni2+含量同时进行了测定.通过对网络结构和参数的优化,提高了测定的准确性,Fe2+和Ni2+的浓度在一定范围内与峰高呈线性关系,实验结果令人满意.
【Abstract】 The back propagation artificial neural network was applied to the process of flow injection spectrophotometer date of copper alloy by optimizing the network structure and parameters.The predication accuracy was improved.It achieved the simultaneous determination of Fe(Ⅱ)and Ni (Ⅱ)in copper alloy when they are separated.The Fe(Ⅱ)and Ni(Ⅱ)appear linear within the individual limits of 0.1~7.5 μg/mL and 0.1~6.00 μg/mL concentration.
