A carbon paste electrode modified with multi-walled carbon nanotubes (MWCNT) was prepared and the determination of ultra trace amount of zirconium based on the anodic adsorptive voltammetry of the zirconium-calcium-alizarin red S mix-polynuclear complex is described in this paper for the first time. The results showed that the sensitivity and the selectivity of the method are excellent. The second derivative linear scan voltammograms of the complex were recorded by polarographic analyzer from 200 to 1200 mV (vs. SCE) and it was found that the c...

与多围的碳 nanotubes (MWCNT ) 修改的一个碳浆糊电极被准备，锆的极端踪迹数量的决心第一次在这篇论文基于 zirconium-calcium-alizarin 红 S 混合多核的建筑群的阳极的吸附的 voltammetry 被描述。结果证明敏感和方法的选择是优秀的。第二衍生物建筑群的线性扫描 voltammograms 被 polarographic 分析器从 200～1200 mV 记录(对 SCE )并且建筑群能在电极的表面上被吸附，这被发现，在大约 840 mV 产出一座山峰，相应于在建筑群的艺术的氧化。山峰水流在 6.0 ×1 的范围与 Zr ( IV )集中线性地增加 0 −12-6.0×10−11摩尔 ·L −1(累积时间 120 s )， 6.0 ×1 0 −11-2....
