The electrolytic cell device is used for an electrochemistry analytical instrument and specially applicable to the detection of ion content in the heavy metal; the processes of stirring, collecting and measuring a solution to be tested are controlled by software; and the electrolytic cell device has stable rotation speed, stirring uniformity, high rate, measurement accuracy, good repeatability, high automation degree, small volume and carrying convenience, does not need alternating-current power supply and is suitable to application in the wild.
Description
Technical field
The utility model relates to a kind of determining heavy metals electrolytic cell device, belongs 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 have classified it as standard detecting method, as 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 to 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 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 on the market this type of direct current supply and fully by the stirring of software control, enrichment, measurement with the determining heavy metals electrolytic cell device.
The utility model content
The purpose of this utility model is to provide a kind of being easy to carry, and is suitable for field studies, and measurement result is accurate, can realize the determining heavy metals electrolytic cell device of automation mechanized operation.
The technical solution of the utility model is: the determining heavy metals electrolytic cell device, comprise electrolytic cell, three electrodes, its improvements are that described electrolytic cell is arranged in the shell that has base, three electrodes are installed on the electrolytic cell top cover, 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: described 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; Described disk working electrode contacts with the carbon brush that is positioned at outer cover by connecting link; Described 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.
In the utility model, each component groups 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 the speed height stirs, and measurement result is accurate, favorable reproducibility.This device is connected with software control part, can realize automation mechanized operation.
Determining heavy metals described in the utility model 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 using method is: pour solution to be measured into electrolytic cell, with mineral acid or inorganic salts is supporting electrolyte, connect 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 adds known quantity then in solution to be measured is measured.After measurement finishes, respectively deduct the current curve (deduction blank) of blank solution, promptly will accurately try to achieve 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.
