摘要:

以TritonX-100为增溶、增敏剂,以5-Br-PADAP为显色剂,建立了同时测定废水中Cu(Ⅱ)、Fe(Ⅲ)、Ni(Ⅱ)、Fe(Ⅱ)的多波长线性回归分光光度法,并应用于模拟废水以及实际废水中Cu(Ⅱ)、Fe(Ⅲ)、Ni(Ⅱ)、Fe(Ⅱ)的测定,加标回收率均在96%和104%之间,结果令人满意。

Abstract:

A method for simultaneous determination of Cu(Ⅱ), Fe(Ⅲ), Ni(Ⅱ)and Fe(Ⅱ)by multi-wavelength linear regression spectrophotometry with 5-Br-PADAP in the presence of TritonX-100 had been established. The proposed method had been applied to the determination of Cu(Ⅱ), Fe(Ⅲ), Ni(Ⅱ)and Fe(Ⅱ)in simulated and true wastewater respectively with satisfactory results. Both of the recovery rates of Cu(Ⅱ), Fe(Ⅲ), Ni(Ⅱ) and Fe(Ⅱ)are between 96% and 104%.
