The potentials of Pt-black electrode using a copper conducting wire instead of the salt bridge in acid and alkaline solutions
without the use of H2 evolution reactions were measured. There were three nonlinear portions in the calibration curve. Unusually,
the potential slopes at pH 3–5 and 8–10 indicated 200 mV and 70 mV per pH, respectively. Such high sensitivity for pH slope,
more than 4 times of usual 59 mV per pH, may be credited to the special properties of the Pt-black surface. SEM (scanning
electronical microscopy) was applied to characterize the surface of the Pt-black electrode. Its working mechanism is well
explained in the theory of capacitance potentials rather than Nernst’s redox potentials. 相似文献

超滤在反渗透预处理工艺中的应用 总被引:7,自引:0,他引:7
以UF替代传统的预处理工艺,解决了RO制水系统预处理难的问题。试验结果表明:UF可把原水的SDI(或FI)指数由8-10降至接近于零,对水中的悬浮物,金属氧化物,胶体,有机物,菌类都有良好的去除效果,可完全满足RO系统对预处理水质的要求。本文重点讨论UF作为RO预处理的工艺;UF对水中杂质的脱除效果及运行性;UF膜通量的衰减规律及恢复。 相似文献
