| Abstract |
The model 1206 Orion Research cyanide monitor was investigated using the Orion specifications and environmental considerations as a guide. Laboratory tests under controlled environmental conditions showed the electronic stability (drift) to be within 0.1% over the temperature range of 5C to 35C. Sensor stability, over the temperature range 5C to 35C was tested by applying free cyanide ion (standard solutions of 1 mg/l and 10 mg/l) as direct input to the monitors. Dynamic on-stream measurements were made from a metal plating process rinse stream in a field installation of the monitor, and these measurements were periodically compared with those of the standard method for total cyanide. This field installation revealed the comparisons were widely variable. Steady-state comparisons were made of field-collected samples with the standard method for determining total cyanide. These tests revealed that a 15% to 20% loss in cyanide concentration resulted from the required straining and filtering of the sample input to the monitor. |
