The purpose of this utility model is to provide the devices that a kind of liquid detecting analyzes dithionate, reduce artificial detection
Error, pass through automatic detection improve detection accuracy and efficiency.
The utility model solve above-mentioned technical problem technical solution be:
A kind of device of liquid detecting analysis dithionate, including nitrogen cylinder, gas flowmeter, three neck round bottom flask,
Condenser pipe, triangular flask group and Quick testing instrument;Three neck round bottom flask includes 2 side bottlenecks and 1 top bottleneck, triangular flask group
The first triangular flask, the second triangular flask and third triangular flask including passing sequentially through connecting tube connection;Nitrogen cylinder by connecting tube with
The air inlet of gas flowmeter is connected to, wherein 1 side that the gas outlet of gas flowmeter passes through connecting tube and three neck round bottom flask
The connection of portion bottleneck, the top bottleneck of three neck round bottom flask are provided with condenser pipe, and the top exit of condenser pipe passes through connecting tube and the
One triangular flask is connected to, and the bottle mouth position of third triangular flask is provided with escape pipe;Magnetic agitation heating bottom is provided on Quick testing instrument
Seat, three neck round bottom flask are positioned on magnetic agitation heated base.In addition, it is provided with display screen on the shell of Quick testing instrument,
For showing time and voltage;It is additionally provided with adjusting knob, for adjusting voltage and rotating speed.
Now by taking the principles of chemistry for measuring manganous dithionate as an example, illustrate that the utility model measures the mechanism of dithionate.
(1)MnS2O6
MnO2+2SO2→MnS2O6
There is two kinds of desulfurization methods in sweetening process, with MnO2And SO2Direct oxidation reduction reaction based on;
(2)MnCO3
SO2+H2O→H2SO3
H2SO4+MnCO3→MnSO4+CO2↑+H2O
In sweetening process, SO2Initial oxidation is sulfuric acid, then again with MnCO3Reaction, therefore, the leaching of manganese under anaerobic
Extracting rate is relatively low;
(3)Mn2O3
SO2+H2O→H2SO3
H2SO4+Mn2O3→MnSO4+MnO2+H2O
Mn2O3+2SO2→MnSO4+MnSO3
MnO2+SO2→MnSO4
Sweetening process is with Mn2O3Same SO2Reaction generates MnSO4And MnSO3Based on, while with Mn2+Catalysis oxidation SO2It generates
Sulfuric acid, the sulfuric acid for reacting generation continues and Mn2O3Reaction generates MnSO4And MnO2, MnO2Again with SO2Reaction, thus, aerobic
Under conditions of, reaction improves 1 times.
Having the beneficial effect that for dithionate device is analyzed using the utility model liquid detecting, is replaced by inert nitrogen
Sulfur dioxide and method using liquid detecting analysis, accurately detect dithionic acid salt ion in water solution system and
The content of sulfite ion;Using the fast detector for being provided with magnetic force heating stirring so that detection it is more quick, accurately and
Automation;Artificial detection existing error and cost problem in the process are reduced, detection efficiency is improved, is the complete of subsequent technique index
At laying the foundation, the maximization of enterprise profit is realized.
