阳极溶出伏安法便携式重金属分析仪性能测试方法研究

Research on Metrological Characteristics Testing Method for Anodic Stripping Voltammetry Portable Heavy Metal Analyzer

阳极溶出伏安法便携式重金属分析仪被广泛应用于水体、土壤、食品、固态物质的重金属含量检测。除镉、铅、铜外,使用该分析仪检测砷、汞、锌、铬、锰、镍、锡、铊、铁、钴、硒、银、碲、金、铋等重金属时,需选择合适的计量性能测试项目及测试方法。同时,JJF 2037-2023《便携式溶出伏安法重金属检测仪校准规范》对测量镉、铅、铜元素的便携式溶出伏安法重金属检测仪的计量特性及校准方法做出了要求。

Anode stripping voltammetry portable heavy metal analyzer is widely used in the determination of heavy metal content in water, soil, food and solid substances.In addition to cadmium, lead and copper, when the analyzer is used to detect heavy metals such as arsenic, mercury, zinc, chromium, manganese, nickel, tin, thallium, iron, cobalt, selenium, silver, tellurium, gold and bismuth, appropriate metrological performance test items and test methods should be selected.At the same time, JJF 2037-2023 "Calibration Specifications for Portable Stripping Voltammetry Heavy Metal Detectors" has made requirements for the metrological characteristics and calibration methods of portable stripping voltammetry heavy metal detector for measuring cadmium, lead and copper elements.
