Total cyanide measurement of wastewater samples by a UV digestion and gas diffusion technique coupled with amperometric detection


Cyanide (CN -) is a highly poisonous ion that binds with the enzyme cytochrome C oxidase. This complex inhibits cellular respiration and energy production, resulting in cytotoxic hypoxia affecting the central nervous system (CNS) and heart. Death typically occurs from respiratory arrest following CNS failure.


Systea’s FLOWSYS III System from Lab Solutions


measures total cyanide by a UV digestion and gas diffusion technique coupled with amperometric detection in accordance with ASTM Method D 7511-09e2.


This non-distillation technique is particularly effective for applications where thiocyanate is present to avoid cyanide loss or positive interference. ASTM D 7511-09e2 is USEPA- approved for analysis of wastewater samples for NPDES compliance reporting.


Lab Solutions’ website provides updated information on collecting and preserving samples, analytical interferences, and new ASTM and USEPA analytical methods.


Cyanide compounds are used in a wide range of industrial applications. Hydrogen cyanide is used in the production of nylon 6/6 and methyl methacrylate plastics. Potassium or sodium cyanide are used in mining operations to leach gold from ore. Cyanide salts are used in metal plating baths for electroplating of brass, bronze, cadmium, copper, gold, silver and zinc. Other industrial processes employing cyanide include; petroleum refining, steel production, microelectronics manufacturing, specialty chemical and pharmaceutical production. The acute toxicity and wide spread industrial usage of cyanide makes environmental testing critically important. Intentional contamination of drinking water or food products with cyanide is also a potential domestic security threat.

54843pr@reply-direct.com Low maintenance UV nitrate sensor


Responding to global demand for improved monitoring of nitrate in freshwater, OTT HydroMet has launched an optical nitrate sensor, the OTT ecoN, specifically for use in environmental surface and groundwater applications. “This is fantastic news for scientists, catchment managers, water companies, regulators and environmental consultants,” says Peter Schaeffeler, Product Lifeycle Manager at OTT HydroMet. “In the past, customers have been caught between low-cost/ limited-performance sensors and high-end technologies, for which purchase costs prevent large scale deployment. The OTT ecoN neatly fills that gap; as a continuous nitrate monitor, with minimal maintenance requirements, it can be left to monitor in remote locations, and an optional wiper makes it suitable for extended deployments.”


In addition to a low purchase cost, the OTT ecoN also lowers the cost of ownership because it is factory calibrated for life. With automatic drift compensation, zero baseline checks with ultrapure water are quick and easy to perform and are only required as an occasional test of instrument function.


The OTT ecoN measures nitrate by the absorption of UV light at 212 nm and removes the possible effects of organics and turbidity by similar measurements at 254 nm and 360 nm respectively. As an optical sensor, the OTT ecoN provides high accuracy and low resolution without the drift and interferences of ion-selective electrodes, or the ongoing reagent and maintenance costs of wet-chemistry analysers.


The OTT ecoN can transmit data via an SDI-12 interface due to the new OTT ecoN Modbus to SDI-12 Converter. The converter translates the Modbus protocol for the OTT ecoN nitrate sensor to allow for easy and continuous remote data access. Remote configuration can be achieved as well, to export data and configure the OTT ecoN via a web interface.


No specialised software is necessary to communicate with the OTT ecoN – a simple, intuitive browser-based user interface is accessed by connecting a small interface unit to the sensor.


Measurements can be stored internally within the sensor, but as a specialist in sensing, datalogging and telemetry, OTT HydroMet can supply the most appropriate monitoring system for every application. This includes the choice of sensor, because the OTT ecoN is available with different cell pathlengths to ensure optimum performance across all measurement ranges. However, OTT HydroMet is also able to conduct a retrospective change of optical path length when customers need to change application, such as moving it from very turbid surface water to groundwater for example.


Summarising, Schaeffeler says: “Nitrate is an extremely important contaminant of fresh surface and groundwater; causing health issues in humans and playing a major role in eutrophication and the proliferation of algae. It is therefore essential that the role of nutrients is fully understood and that water professionals are able to access accurate, reliable data on nutrient sources and loading, as well as being provided with alarms when pollution events take place.


“The OTT ecoN has proven extremely accurate and reliable in the field, and has been priced for extensive deployment, so we are very excited with the prospects for this technology.”
