Automated Potentiometric Techniques for the On-Site Monitoring of Ions Important in Water Quality Control

摘要

The characteristics of the nitrate electrode - fluoride electrode cell without liquid junction were investigated for applicability to nitrate ion analysis. In addition to enabling accurate nitrate analysis, the cell was found to be useful for examining the effects of interfering ions. An attempt was made to use the nitrate electrode in following nitrate ion uptake by algal cultures. The algae interfere to a certain extent with the electrode response. Using knowledge gained from research under this grant, a potentiometric nitrate analysis capability has been set up at the new University of Missouri Environmental Trace Substances Laboratory.
