Abstract
The invention discloses an electrolytic bath device for heavy metal measurement, belongs to the field of electrochemical analyses, and is characterized in that an electrolytic bath is arranged in a housing with a base, wherein three electrodes are mounted on the top cover of the electrolytic bath; a disk working electrode of the three electrodes is connected with the output shaft of a DC direct current motor; and an outer cover is arranged outside the motor. The electrolytic bath device is used for electrochemical analytical instruments, and is particularly suitable for measuring the content of heavy metal ions; the stirring, enrichment and measurement processes of a to-be-measured solution are controlled through software, the rotational speed is stable, the stirring is uniform, the rate of speed is high, the measurement is accurate, the repeatability is good, and the degree of automation is high; and the electrolytic bath device has a small size, is convenient to carry, doesn't need AC alternating current power supply and is suitable for field application.
Description
Technical field
The present invention relates to a kind of determining heavy metals and use electrolytic cell device, belong to the electrochemical analysis technical field.
Background technology
The galvanochemistry dissolving-out technology is with its extremely low cost and highly sensitive characteristics; Just replacing the heavy metal ion monitoring that traditional atom absorption method is widely used in factory effluent, sanitary wastewater, drinking water source, drinking water, surface water, seawater, environment water etc. the America and Europe at present, the content of beary metal that also is widely used in the extracts such as soil, food, beverage, solid waste detects.Authoritative institutions such as U.S. EPA classify it as standard detecting method, like EPA7198,7063 and 7472 etc.
At present, the galvanochemistry dissolving-out technology is measured general stirring, enrichment and the measuring process that adopts independent magnetic stirrer and electrolytic cell to combine and realize solution to be measured of heavy metal.The beginning of this stirring and enrichment, measuring process all needs control manually with end, and automaticity is low; And, also cause easily because the stirring rate problem of non-uniform that voltage instability brings owing to adopt exchange way to supply power to magnetic stirrer; Simultaneously, because magnetic stirrer requires Alternating Current Power Supply, this also makes the field studies of portable instrument be restricted.All these have all greatly limited the operability of ease for operation, measurement result repeatability and the field studies of instrument.At present, also do not see this type of direct current supply and use electrolytic cell device by stirring, enrichment, the measurement of software control with determining heavy metals fully on the market.
Summary of the invention
The object of the present invention is to provide a kind of being easy to carry, be suitable for field studies, measurement result is accurate, can realize that the determining heavy metals of automation mechanized operation is used electrolytic cell device.
Technical scheme of the present invention is: determining heavy metals is used electrolytic cell device; Comprise electrolytic cell, three electrodes; Its improvements are that said electrolytic cell is arranged in the shell that has base, and three electrodes are installed on the electrolytic cell top cover, and this device is provided with direct current generator; The disk working electrode in three electrodes and the output shaft coupling of direct current generator, this device is connected with software control part.
Further scheme is: said direct current generator is installed on the support that is fixed on the electrolytic cell top cover, and there is outer cover the motor outside; Said disk working electrode contacts with the carbon brush that is positioned at outer cover through connecting link; Said electrolytic cell top cover becomes removable jew to be connected with the port of shell, and top cover is provided with injection port and air hole.
Among the present invention, each component sets is dressed up one, has saved the magnetic stirrer in original measurement mechanism, and compact conformation, volume are little, easy to carry.Used motor is a direct current generator, does not need Alternating Current Power Supply, avoids the phenomenon of voltage instability, is fit to field studies, and motor speed is stable, and speed is high, stirs, and measurement result is accurate, favorable reproducibility.This device is connected with software control part, can realize automation mechanized operation.
Determining heavy metals of the present invention can be used for electrochemical analytical instrument with electrolytic cell device; Be specially adapted to the instrument that portable heavy metal ion content detects; Concrete method of application is: pouring solution to be measured into electrolytic cell, is supporting electrolyte with mineral acid or inorganic salts, connects three electrode wires; In software, set each experiment parameter, carry out stirring, enrichment and the measurement of heavy metal ion.Survey blank solution and survey during measurement earlier and treat solution, the standard specimen that in solution to be measured, adds known quantity is then measured.After measurement finishes, respectively deduct the current curve (deduction blank) of blank solution, promptly will accurately try to achieve the heavy metal ion content in the solution to be measured by standard addition method then by the current curve of solution behind solution to be measured and the mark-on.
