Abstract |
The Orion fluoroborate electrode was evaluated to determine its applicability to water and waste. The calibration curve was Nernstian down to 0.6 mg/l and the slope of the curve was 56 millivolts per decade change. Interference of nitrate and sulfate was studied. Low results were obtained for samples that contained 50 mg/l of sulfate and 10 mg/l tetrafluoroborate or 10 mg/l sulfate and 1 mg/l tetrafluoroborate. To determine 1 mg/l of tetrafluoroborate, nitrate should be absent. The fluoroborate electrode can be used directly to determine some selected fluoroborates. |
