看到一篇文献，是这样说的，After it was thoroughly rinsed with double distilled water, a potential of + 1.75 V was applied to the electrode in 0.1 M pH 5.0 PBS for 300 s. The electrode was then scanned between + 0.3 and + 1.3V until a steady-state current – voltage curve was obtained.? ? 玻碳电极经过上述的处理为什么会在其表面产生羧基呢？ 显示全部
