【摘要】 在ＰＨ４．７的醋酸盐缓冲体系中，用单扫示波极谱法可获得灵敏的Ｍｎ（Ⅱ）——芦丁（Ｒｔ）络合吸附波，锰浓度在１．０×１０－７～１．０×１０－５ｍｏｌ．Ｌ－１范围内与二阶导数波峰高有正比关系，检测限为８．０×１０－８ｍｏｌ．Ｌ－１。测得电活性络合物组成为Ｍｎ（Ⅱ）：Ｒｔ＝１∶１，条件稳定常数β＝２．３×１０６。更多还原

【Abstract】 In the baffer solation of acetate,at PH4.7,a sensitive adsorptive complex wave of Mn(Ⅱ) Rutin can be obtained by single-sweep polarography.The detection limit was down to 8.0×10 -8 mol.L -1 .The complex composition is detected as Mn(Ⅱ)Rt=1:1.更多还原
