  • Fabrication of a needle-type pH sensor by selective electrodeposition
    The main advantages of IrOx in comparison with other pH sensitive films include a wider pH response range , high sensitivity, and low redox pair interference.8 The half-cell potential generated at the inter- face between the electrodeposited IrOx and the electrolyte... The previously reported ORP and DO micro electrode array sensors used a gold electrode surface for measurement.
  • Microbial sulfate reduction and metal attenuation in pH 4 acid mine water
    At lower pH it is possible that higher dissolved H2 concentrations are able to accumulate due to slower rates of sulfate reduction. Direct measurements of ORP (by platinum electrode ) indicated Eh values from 0.35 to 0.51 V in the deep (≥ 75... ...Eh values from speciation calculations based on measured concentrations of Fe(II) and Fe(total) ranged from 0.51 to...
  • Stannous chloride—an effective reducing agent for the removal of selenium(IV) from acidic solution
    The oxidation reduction potential ( ORP ) and pH of the solution were monitored using a gold double junction electrode (Cole-Parmer EW-27 013-45) and a Corning high performance pH electrode (37–476 146) respectively. Whenhigherprecisionwasneededatthelowconcentration range , a graphite furnace AAS was used.
  • An automatic monitoring network installed in Tuscany (Italy) for studying possible geochemical precursory phenomena
    As to the high - impedance electrodes ( pH and ORP measurement), a differ- ential electrometer (an amplifier with a very low input current loss) has been custom designed to meet high specifications exceeding the usual market availability. The electrometer provides three-port isolation and operates over a wide tem- perature range ; in particular, care...
