Abstract: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 600nm, and pHrange was 8.8~10.6. In the trace range of Cu, Zn,Mn from 0~1.6×10-6g/mL the beer' s law was obeyed. The detection limit was 10-8g/mL. The recovery ratio was 98%~103%.
Key words: factor analysis simultaneous determination of Cu, Zn, Mn photometric analysis
