Problems solved by technology

However, metal electrodes are relatively expensive and are easily affected by the acidic environment of the liquid to be analyzed; and, during XRF analysis, the metal matrix of the metal electrode will interfere or affect the analyzed electrodeposited metal elements, resulting in the analysis of Results for metallic elements are inaccurate, therefore, there is a so-called "substrate effect" problem
[0004] In addition, there is also the use of conductive synthetic diamond materials as cathode electrodes in the electrochemical deposition process. Similarly, conductive synthetic diamond materials are costly and difficult to process (for example, doping is required to achieve the conductive properties of diamond)

Abstract

The invention provides an electrochemical deposition device and an X ray fluorescence spectrum analysis system, and belongs to the technical field of electrochemical deposition. The electrochemical deposition device comprises a container for accommodating a liquid to be analyzed, a conductive carbon-based material layer serving as a cathode electrode is fixed in the container or part of the wall of the container, and metal elements to be analyzed in the liquid to be analyzed are adhered to the carbon-based material layer in the electrochemical deposition process.

Description

technical field [0001] The invention belongs to the technical field of Electrochemical Deposition, and relates to an electrode using a conductive carbon-based material layer, the use of the carbon-based material layer, a container with the electrode fixed thereon, and an electrochemical deposition device using the container. It relates to an X-ray fluorescence spectroscopic analysis (X-Ray Fluorescence, XRF) system using the electrochemical deposition device and a method for analyzing the content of metal elements in liquid. Background technique [0002] In order to analyze the content of metal elements (such as Hg, Pb, Cd, As, Ni or Cr, etc.) in liquids (such as water bodies), one of the common ways is to use electrochemical deposition methods. Specifically, the metal elements in the water body (usually in the form of ions) are electrodeposited on the cathode electrode by electrochemical deposition, and then X-ray fluorescence spectroscopy (X-Ray Fluorescence, XRF) analysis...
