Problems solved by technology

[0004] However, in the electrochemical electrolytic cell with stirring function provided by the prior art, the electroplated mercury film or bismuth film on the working electrode will fall off when stirring; and the working electrode is built in the stirring rod, increasing The distance between the working electrode and the counter electrode is increased; thereby reducing the efficiency of the current transmission of the electrolytic cell, which in turn makes the electrochemical electrolytic cell less accurate in detecting heavy metal ions

Abstract

The invention provides an electrochemical electrolytic cell which comprises a solution containing device, a working electrode and a reference electrode which are arranged in the solution containing device, a stirring device in the solution containing device, and a heating device in the stirring device, wherein the working electrode and the reference electrode are distributed on two sides of the stirring device. According to the electrochemical electrolytic cell provided by the invention, the heating device is arranged in the stirring device, so that the electrochemical electrolytic cell can simultaneously achieve stirring and heating functions, and has stable electrochemical reaction conditions in the working process. Therefore, the electrochemical electrolytic cell provided by the invention is high in accuracy in the process of detecting heavy metal ions.

Description

technical field [0001] The invention relates to the technical field of electrolytic cells, in particular to an electrochemical electrolytic cell. Background technique [0002] Heavy metals mainly refer to metals or metalloids such as mercury, cadmium, lead, chromium, arsenic, etc., and also refer to general metals with certain toxicity, such as copper, zinc, nickel, cobalt, tin, etc. Heavy metals are enriched in the surrounding environment of human beings, enter the human body through the atmosphere, water, food, etc., and accumulate in some organs of the human body, causing chronic poisoning and endangering human health. Therefore, the detection of heavy metals has become the focus of attention. At present, heavy metal detection methods mainly include atomic absorption spectrometry, ultraviolet-visible spectrophotometry, atomic fluorescence method, electrochemical method, X-ray fluorescence spectrometry, etc. Among them, electrochemical method is a kind of heavy metal dete...
