The Deep Carbon Cycle
Over billions of years, the total carbon content of the outer part of the Earth—in its upper mantle, crust, oceans and atmospheres—has gradually increased, scientists report.
Profiling DNA Viruses in Arctic Lakes
The Arctic's freshwater lakes contain viral communities composed of DNA viruses from lineages that are largely distinct from those described elsewhere, a new study suggests.
Unravelling the Mysteries of Carbonic Acid
Researchers have shown how gaseous carbon dioxide molecules are solvated by water to initiate the proton transfer chemistry that produces carbonic acid and bicarbonate.
Algal Blooms Pose Health Risks Downstream
A new study has found that toxic algal blooms in reservoirs on the Klamath River can create unsafe water conditions far downstream on lower parts of the river in northern California.

Determination of Total Cyanide in Municipal Wastewater and Drinking Water Using Ion-Exclusion Chromatography with Pulsed Amperometric Detection (ICE-PAD)

Dionex Corporation

Cyanide is regulated as an environmental contaminant by the US EPA for drinking water, surface water, and wastewater due to these health concerns.

Total cyanide is defined by the US EPA as free cyanide ion and complex cyanides that are converted to hydrocyanic acid (HCN) during strong acid digestion. More recently, total cyanide also includes ferrocyanide and ferricyanide due to free cyanide formed by exposure to light.7 For drinking and surface waters, the US EPA has established a maximum contamination level (MCL) of 200 μg/L free cyanide determined by a total cyanide assay. To determine total cyanide, the sample is digested
with sulfuric acid to convert the cyanide to hydrogen cyanide gas, aspirated into a strong caustic solution, then assayed.

In this Application Note, the authors describe a method with PAD using a Pt disposable working electrode and a waveform optimized for determination of total cyanide in drinking and wastewater.
