摘要
贵金属金和钯都能与新试剂5-(2-羟-基3,5-二甲基苯偶氮)罗丹宁(HD-PAR)形成稳定的红色络合物,由于二者吸收峰严重重叠,采用化学计量学中的人工神经网络方法实现了金和钯的同时测定,方法可用于废水中金和钯的同时测定。
A new highly selective reagent 5-(2-hydroxy-3,5-dimethyl-phenylazo)-rhodanine can react with Au (Ⅲ) and Pd( Ⅱ ) to form a stable red complex with maximum absorption at 510 nm. Since the absorption spectra were seriously overlapped. In this paper, An artificial neural network-spectrophotometry method for simultaneous determination of Au( Ⅲ ) and Pd( Ⅱ ) in waste water was studied. The results are satisfactory.
