Detection of trace levels free cyanide in surface water with the San++ Continuous flow analyzer
The Fraunhofer institute, for molecular and applied ecology IME in Germany, has written an interesting article in their Annual Report of 2016-2017 about measuring background levels of free cyanide in surface water with our San++ Continuous flow analyzer.
Surface waters: Measuring background levels of free cyanide
Free cyanide is highly toxic towards aquatic organisms. Environmental quality standards for free cyanide were recently proposed under the European Water Framework Directive. However, current detection methods are not sensitive enough to measure the proposed levels accurately. Fraunhofer IME researchers have adapted an existing analytical method for free cyanide and investigated background concentrations in surface waters to facilitate compliance testing.
