摘要

Field experiments were carried out at a flowing well in the Salton Sea Geothermal Field to study the influence of electrical potential on scale deposition. The scale is com¬posed mainly of silicon, iron, copper, silver, and aluminum. Significantly more scale formed on negative than on either positive or neutral electrodes. The scale on the cathode contained up to 1000 times more lead than the scale on the other electrodes. It may also contain slightly increased amounts of copper. Although the amount of scale on positive and neutral electrodes appeared to be the same, the scale on the positive electrodes was richer in iron and zinc. X-ray powder diffraction reveals the presence of lead as Pb(0H)Cl and of iron as FeOOH. No crystalline silicon forms were detected. Collectively, the results suggest that both iron and lead are present in complex ionic forms in solution.
