Fluoride and Iodide Selective Electrodes Applied to Oilfield Brine Analysis

摘要

Selective ion electrodes were used to develop methods to analyze oilfield brines for fluoride and iodide. Knowledge of the concentrations of these ions is needed in enhanced-oil-recovery research, environmental impact studies, and in locating valuable recoverable elements such as iodine and lithium. The methods developed can be used to determine fluoride and iodide as low as 0.25 mg/l and 10 mg/l, respectively. (ERA citation 04:012423)
