| titleOfInvention | Method for analyzing silicic acid in geothermal steam |
| abstract | PURPOSE:To determine quantitatively the silicic acid in the geothermal steam by oxidizing the H2S in the test water prepd. by cooling and condensing the geothermal steam to H2SO4 by using an oxidizing agent to eliminate the disturbing effect then detecting the silicic acid by a molybdenum blue absorptiometric method. CONSTITUTION:The oxidizing agent such as KBrO3 is added to the test water prepd. by cooling and condensing the geothermal steam to oxidize the H2S in the test water to H2SO4 to conceal the same. This operatio can be carried out thoroughly in several minutes at a room temp. Ammonium molybdate is added to the test water subjected to such oxidation treatment and is mixed therewith. A tartaric acid soln. is added to the water after resting for 5min to conceal the PO4<-> in the test water and thereafter a reducing agent, for example, L-ascorbic acid soln. is added thereto. The coloration of the formed molybdenum blue is measured by spectrophotometry and the quantity of the silicic acid in the test water is determined from the preliminarily formed calibration curve. The H2H is thus easily and quickly concealed and the silicic acid in the geothermal steam is quantitatively determined with good accuracy, by which the control to prevent the formation of scale as a result of the deposition of the silicic acid in a geothermal power plant is made easy. |
