铁-3,5-二溴-PADAT络合物吸附波 ADSORPTIVE POLAROGRAPHIC WAVE OF IRON-3, 5-diBr-PADAT COMPLEX 高军 1 first-author 徐勉懿 1 潘祖亭 1 孟凡昌 1 黄石市水质监测站 黄石市水质监测站 研究了醋酸—醋酸钠底液中铁-3,5-二澳-PADAT络合物吸附波。Fe（Ⅲ）的检出限为5ppb,线性范围0～500ppb。本法的精密度和准确度都很好,但等量以上的铜干扰测定。 The polarographic adsorptive wave of iron-3, 5-diBr-PADAT complex in the solution of HAc-NaAc has been researched. Ep=-0.43V（vs. SCE）. The determination limit is 5 ppb. The line range is 0-500 ppb. This method has been used to determination of trace amounts iron in aluminium alloy and some foods, tap water. It is selective except copper. The behaviour and mechanism of the adsorptive wave have been studied and discussed. The adsorptive wave is probably caused by adsorption of the complex of Fe-3, 5-dibr-PADAT, followed by reduction of the ligands. 痕量分析 铁 3,5—二溴—PADAT 极谱络合物吸附波 determination of trace amount iron 3 5-diBr-PADAT Polarographic adsorptive wave of complex 1987-02-01 2021-04-01 2
