摘要
用分光光度法采用１－（２－吡啶偶氮）－２－荼酚作显色剂，用目标检测因子分析程序处理数据，不经分离和富集同时测定铜锌锰三组分混合体系。选择波长范围５００～６００ｎｍ，ｐＨ８．８～１０．６。线性测定范围为０～４０×１０－５ｇ／２５ｍＬ，检测限为１０－８ｇ／ｍＬ，回收率为９８％～１０３％
A method for simultaneously spectrophotometric determination of Cu,Zn, Mn in their mixture by factor analysis of target testing has been developed. 1 (2 pyridylazo) 2 naphthol was used as development reagent. The selected wavelength range was from 500 to 600 nm, and pH range was 8.8～10.6. In the trace range of Cu, Zn,Mn from 0￣1.6×10 -6 g/mL the beer's law was obeyed. The detection limit was 10 -8 g/mL. The recovery ratio was 98%￣103%.
