Cyanide Drinking Water Contaminants, Facts/Removal Methods
The MCLG for cyanide has been set at parts per million (ppm) because EPA believes this level of protection would not cause any of the potential health problems described below Based on this MCLG, EPA has set an enforceable standard called a Maximum Contaminant Level (MCL)....

Elution and Carbon Reactivation Resource book
no gold in solution and is therefore able to extract most of the remaining gold, bringing the total gold recovery (for both steps) up to 97%. A split system is used to achieve the highest possible gold grade in the final solution and also to minimise both electrowinning solution volume and potable water consumption. Elution Tanks...

The concentration of the cyanide in the transferred to a measuring flask and distilled water was added to solution was measured as a function of mixing intensity, as shown make up a total volume of 1000 ml. in Fig. 1, which shows the effect of mixing velocity on cyanide removal at different mixing times....
Determination of Cyanide in Blood by IsotopeDilution Gas ...
Background: Cyanide (CN) is a lethal toxin. Quantification in blood is necessary to indicate exposure from many sources, including food, combustion byproducts, and terrorist activity. We describe an automated procedure based on isotopedilution gas chromatography–mass spectrometry (ID GC/MS) for the accurate and rapid determination of CN in whole blood....
