Filed:

Nov 12, 2004

Appl. No.:

10/987579

Inventors:

James Partridge - Waynesville NC, US
Jeffery Partridge - Venice FL, US
D. Gillam - Asheville NC, US

Assignee:

CHEMTRONIX INC. - Waynesville NC

International Classification:

G01N033/00

US Classification:

422062000, 436055000

Abstract:

Apparatus and methods for monitoring of dissolved (ionic) heavy metal residuals in liquid process stream or liquid waste (effluent) streams, as examples, after recovery and collection of such metals from a laboratory, medical, industrial or manufacturing process stream. An automatic controller is employed to deliver a sample volume of liquid from the stream to a measurement chamber, adjust the conductivity of the sample volume within the measurement chamber to a predetermined conductivity at a predetermined conductivity measurement temperature, employ an ion specific electrode and a reference electrode to make a voltage measurement representative of the concentration of specific metal ions within the sample volume at the predetermined concentration measurement temperature, record the voltage measurement, and flush the measurement chamber.

US Classification:

75313, 75733, 266101, 266170

Abstract:

A silver recovery and monitoring system including a sensor for transmitting a silver concentration signal in response to the concentration of silver in a fluid, means for determining whether the silver concentration signal indicates the concentration of silver in the fluid to be above a predetermined silver level and for initiating a silver alert signal in response to a determination that the silver concentration signal indicates the concentration of silver in the fluid to be above the predetermined silver level, and means for transmitting a notification signal to a silver monitoring station in response to the silver alert signal.
