Brief introduction
Anodic stripping voltammetry, with its extremely low cost and high sensitivity, is currently replacing traditional atomic absorption methods and widely used in environmental emergency monitoring, tap water detection, electroplating and surface treatment industry wastewater detection, food, pharmaceutical, hospital wastewater monitoring, and other fields in Europe and America. AmericaEPAWhen institutions have listed it as a standard testing method, keep track of the location, such asEPA7063reach7472wait.
2、 Electrode principle
cause100A nanobelt electrode is composed of nanobelt electrodes, and the signals generated by each small electrode are accumulated to enhance the total signal, thereby increasing sensitivity and reducing the lower detection range. No other commercial electrode can be so fast, sensitive, and accurate. The combination of nanobelt electrode and square wave anodic stripping voltammetry can accurately measure Faraday current by subtracting the background current from the measured current, effectively improving the signal-to-noise ratio. This signal processing method further enhances the sensitivity of the instrument, with fast electrode scanning speed and up to10bend over/Seconds, no need for deoxygenation during detection.3、 Main features
