铜—1—（2—吡啶偶氮）—2—萘酚络合物吸附波的研究

A Study on the Adsorptive Wave of Copper-PAN Complex

摘要: 在ＰＨ６．２的ＮａＯＨ－ＫＨ２ＰＯ４介质中，Ｃｕ（Ⅱ）与１－（２－吡啶偶氮）－２－萘酚生成络合物，在线性单扫描示波极谱仪上于－０．２５Ｖ处出现一灵敏络合物吸附波。铜的质量浓度在１－４６０μｇ／Ｌ内与峰高呈良好线性关系，检出限０．５μｇ／Ｌ。

Abstract: In NaOHKH2PO4 medium at pH 6.2, copper() reacts with PAN to form a complex which appears a sharp polarographic wave on DME at -0.25 V (vs. SCE). The peak height is linear with the concentration of copper () in the range of 1460 g/L with detection limit of
