Re(Ⅶ)在各种介质中极谱行为的研究已有很多报道.Letcher曾报道了Re(Ⅶ)在4mol·L~(-1)HClO_4中的极谱还原,认为交流一次谐波极谱(AC_1)波仅在4mol·L~(-1)HClO_4时才得到良好峰形,而在2mol·L~(-1)HClO_4时,AC_1峰达到极大,其后不再随[HClO_4]的增加而上升,但未报告在[HClO_4]更高情况下Re(Ⅶ)的极谱还原.我们研究了ReO_4~-在一系列高氯酸浓度中的直流(DC)、交流(AC_1和AC_2)和微分脉冲(DPP)四种极谱波,并研究了这些极谱电流在各种浓度HClO_4介质中的温度效应,DC波对m、τ等的关系,证明了它们具
There are many reports on the polarographic behavior of Re (Ⅶ) in various media, and Lecher reported the polarographic reduction of Re (Ⅶ) in 4 mol·L -1 HClO_4. (AC_1) wave was only good at 4mol·L -1 HClO_4, whereas at 2mol·L -1 HClO_4, the peak of AC_1 peaked and then no longer increased with the increase of [HClO_4] But did not report the polarographic reduction of Re (Ⅶ) in the higher case of [HClO_4] .We studied the effect of ReO_4 ~ on DC, AC (AC_1 and AC_2) And differential pulse (DPP) four kinds of polarographic wave, and studied the temperature effect of these polarographic currents in various concentrations of HClO_4 medium, DC wave m, τ, etc., proved that they have
