旋转圆盘电极：用电化学方法在控制Pb(II)/PbO2 系统中形

ABSTRACT ：The formation of lead dioxide PbO2, an important corrosion product in drinking water distribution systems with lead-bearing plumbing materials, has been hypothesized to involve Pb(III) intermediates, but their nature and formation mechanisms remain unexplored. This study employed the electrochemical (EC) method of rotating ring disk electrode (RRDE) and quantum chemical (QC) simulations to examine the generation of intermediates produced during the oxidation of Pb(II) to PbO2. RRDE data demonstrate that PbO2 deposition and reduction involves at least two intermediates. One of them is a soluble Pb(III) species that undergoes further transformations to yield 旋转圆盘圆环电极（E7R9 RRDE 318m)/旋转环盘电极 旋转圆盘电极/MSR装置
