Abstract: In the buffer solution of 0.2mol/L HAc-NaAc, at pH 4.5, a sensitive adsorptive complex wave of Sb(III)-rutin can be obtained by using single-sweep polarography. The detection limitis down to 2.0×10-9 mol/L. The mechanism of electrode processeswere studied in detail.
Key words: antimony, rutin, single-sweep polarography
摘要: 在pH4.5的HAc-NaAc底液中,用单扫极谱法可得到Sb(Ⅲ)-芦丁灵敏的络合吸附波。csb在4.0×10-9~5.0×10-6mol/L范围内与其二阶导数波峰高有正比关系,检测限达2.0×10-9mol/L。对络合物的吸附机理和组成进行了研究,测定了有关电极反应的动力学参数。
