人工神经网络-分光光度法同时测定合金钢样中的铈组稀土元素
Simultaneous determination of rare-earth elements from cerium group in alloy steel samples by artificial neural network-spectrophotometry with new reagent dibromo-p-methyl-bromosulfonazo (DBMBSA)
【摘要】 以二溴对甲基偶氮溴磺(DBMBSA)为显色剂,应用人工神经网络原理,结合分光光度法,对吸收光谱严重重叠的铈组5种元素不经分离直接同时测定各自含量,实现了合成样品和合金钢样品中个别分量和铈组总量的测定,并进一步讨论了人工神经网络的结构和参数对结果的影响。
【Abstract】 An artificial neural network-spectrophotometric method for simultaneous determination of each content and the total content of rare-earth elements from cerium group in alloy steel samples with a new chromogenic reagent dibromo-p-methyl-bromosulfonazo (DBMBSA) was studied. The effects of the network structure and the network parameters on the analytical results were discussed. The results were accurate and satisfactory.
