Cyanide Analysis

The New MP-WAD Cyanide Analytical Method

Mike Botz and Emil Milosavljevic are the inventors of the new MP-WAD cyanide analytical method. This new titration method overcomes interferences associated with copper in solution and yields a quantitative analytical result for weak and dissociable (WAD) cyanide.

Classifications of Cyanide

The traditional silver nitrate titration method is negatively affected by copper in solution and yields only empirical analytical results. This problem was addressed by Mike Botz and Emil Milosavljevic in extensive laboratory research and the result is the new MP-WAD method:

• Quantitatively measures WAD cyanide
• Requires no instrument calibration
• Requires no sample dilution
• Involves simple and easy to understand equipment
• Is conducted with inexpensive and widely available equipment
• Yields an analytical result in about 3-5 minutes
• Gives WAD cyanide values within ±5% of the USEPA OIA-1677 WAD cyanide analytical method
• Can be readily adapted for on-line cyanide measurements
• Is already in use at one large gold mining operation

The method is applicable to process solutions where the WAD cyanide concentration is above about 5 mg/L. Read more about the MP-WAD cyanide analytical method in Measurement of Weak and Dissociable (WAD) Cyanide with a Modified Potentiometric Titration.
