Abstract
A kind of manufacture method printed electrode for Portable heavy metal detection, it is characterised in that it includes following step: printing carbon starches conductive layer, chromatography Ag/AgCl reference electrode, chromatography electrode dielectric layer, electroplating surface bismuth thin film, rinse well, dry, load and seal in bag.The present invention can be greatly improved batch and print the repeatability of carbon electrode, solves the problem that repeatability is very poor when same concentration heavy metal ion carries out voltammetry test that prints electrode.This prints electrode and can directly package, and is not required to carry out pretreatment when carrying out field test again, can be used for detecting in water quality the heavy metal ion such as lead, cadmium, copper, zinc.
Description
Technical field
The invention belongs to heavy metal analysis equipment technical field, the most just relate to an a kind of portable huge sum of money
Belong to the manufacture method that instrument prints electrode, it is achieved the field of the heavy metal ion such as lead, cadmium, copper, zinc is quickly detected.
Background technology
Heavy metal ion can produce injurious effects, content of beary metal in detection environment to environment and human body
Significant to environmental conservation, heavy metal instrument is used to liquid in industrial wastewater, river, waterworks
In a kind of environmental protection equipment of monitoring in real time of the contents of heavy metal elements that contains.Liquid can be demonstrated in real time
In the change of the content of heavy metal element that contains, grasping environmental safety for people has and important ginseng
Examine value.
Portable heavy metal detector is of a great variety in the market, but most instrumentation complex steps,
Working electrode needs polishing, and reference electrode needs to safeguard and is difficulty with the quick detection that field is real.For reality
The most really obtaining field quickly to detect, needing to print electrode is applied on Portable heavy metal instrument.But mesh
Before the electrode prepared by processing technology that prints electrode there is also the technical barrier of poor repeatability, cause this problem
Main cause have following two aspects: being first that typography falls behind, manual operations attracts error too much.Its
Secondary is that the reference electrode stability printed electrode is the most bad, the most not only easily causes and prints electrode in enrichment
During produce hydrionic interference, and between Different electrodes, occur the negative degree moved different, cause weight
Metal detector takes peak automatically is forbidden.Print electrode in consideration of it, develop one for Portable heavy metal instrument
Manufacture method necessary, this has important in fields such as nano material, environment heavy metal ion monitorings
Meaning.
Summary of the invention
