本文研究了锑在玻碳金膜电极上的电位溶出分析法。在1.2M HCl介质中,于—0.015V(vs·Ag/AgCl)附近有一锑的良好溶出波;通过一系列的条件试验找到了的一选择性较好的测定微量锑的分析方法,溶出时间与5.0×10~(-7)M到10~(-5)M(或更高浓度范围内)的锑波度有良好的线性关系,检出下限为1.0×10~(-7)M。此外还讨论了各种因素对灵敏度的影响以及本方法在实际应用中的优越性。
In this paper, the potential dissolution analysis of Sb on glassy carbon electrode was studied. In 1.2M HCl medium, there is a good eutectic wave of antimony near -0.015V (vs · Ag / AgCl). A more selective method for the determination of trace antimony was found through a series of conditions tests. The dissolution time It has a good linear relationship with the antimony wave of 5.0 × 10 -7 M to 10 -5 M (or higher), and the lower limit of detection is 1.0 × 10 -7 M. In addition, the influence of various factors on the sensitivity and the superiority of this method in practical application are discussed.
