Description

CO in a kind of high concentration NaOH leacheate2And CO32-The method of removal
Technical field
The present invention relates to atmospheric science technical fields, and in particular to CO in a kind of high concentration NaOH leacheate2And CO3 2-It goes The method removed.
Background technique
In the prior art, mostly be for ion chromatograph analysis zwitterion method, such as CN102749412, with from Anion in sub- chromatography measurement milk.But it is fewer for the method for surveying sugar, and surveyed in the lab using the chromatography of ions When sugared, can mostly encounter has the indissociable situation of 2-3 kind sugar, and this method passes through the CO in removal leacheate2, to reach The purpose for allowing part sugar and sugar alcohol to separate.
Summary of the invention
The present invention provides CO in a kind of high concentration NaOH leacheate2And CO3 2-The method of removal removes in leacheate Carbon dioxide, to achieve the effect that separation sugar and sugar alcohol.
To achieve the above object, present invention provide the technical scheme that
CO in a kind of high concentration NaOH leacheate2And CO3 2-The method of removal, including operate as follows:
1) two mouth flask for preparing certain capacity, connect ultrapure water be placed on it is spare on water-bath type magnetic stirring apparatus, and wherein It is put into clean stirrer, is stirred always in the process；
2) mouth of two mouth flask connects triple valve, and bottleneck, upper termination helium, Centronics port are inserted into the triple valve lower end Connect air extractor；
3) another mouth of two mouth flask connects elbow drying tube, and the bottom end of the drying tube spreads one layer of absorbent cotton, prevents hydrogen Calcium oxide is inhaled into, and enough calcium hydroxide is filled in absorbent cotton upper end, covers one layer of absorbent cotton again on calcium hydroxide, is prevented Only calcium hydroxide sprays；
4) ultrapure water degasification is first given, with air extractor, 30min is persistently evacuated, opens triple valve lower channel, replacement of helium Into flask, in triplicate；
5) temperature control device for opening water-bath type magnetic stirring apparatus, ultrapure water is heated to boiling, is cooled to room temperature；
6) quantitative calcium hydroxide is added in cooling ultrapure water, with 0.25 μm of filter after waiting reactions a period of time Filter ultrapure water；
Prepare two two mouth flasks, equally progress aforesaid operations, then takes one of two mouth flask that sodium hydroxide is added Leacheate is prepared, another two mouth flask is taken to do rinse water.
Carbonate concentration in step 6) ultrapure water is 0.09~0.9mg/L.
Further, in step 6), 0.001g calcium hydroxide is added in every 1L ultrapure water.
The two mouth flask is 2L two mouth flask.
Compared with prior art, the beneficial effects of the present invention are:
Ion chromatograph survey sugar during, influenced by carbon dioxide in leacheate, cannot separate it is some sugar and Sugar alcohol, such as: D-sorbite, trehalose and mannosan, antierythrite and D- threitol.Of the invention is handled by this method Later, to be not completely separated sugar, sugar alcohol separation can improve separation.
Detailed description of the invention

Fig. 2: method flow schematic diagram of the invention.
Fig. 3: separating effect figure is improved.
Specific embodiment
The present invention is further explained in the light of specific embodiments.
(1) with the two mouth flask (such as Fig. 1) of two 2L connect respectively 2L ultrapure water be placed on it is spare on water-bath type magnetic stirring apparatus, It is wherein being put into clean stirrer, is being stirred always in the process；
(2) triple valve is connect flatly wherein, bottleneck, upper termination helium are inserted into triple valve lower end, and Centronics port connects pumping dress It sets；
(3) elbow drying tube is connect in another mouth, drying tube bottom end spreads one layer of absorbent cotton, calcium hydroxide is prevented to be inhaled into, and takes off Enough calcium hydroxide is filled in rouge cotton upper end, covers one layer of absorbent cotton again on calcium hydroxide, prevents calcium hydroxide from spraying；
(4) ultrapure water degasification is first given, with air extractor, 30min is persistently evacuated, opens triple valve lower channel, replace helium Gas is into flask, in triplicate；
(5) temperature control device for opening water-bath type magnetic stirring apparatus, ultrapure water is heated to boiling, is cooled to room temperature；
(6) quantitative calcium hydroxide is added in cooling ultrapure water, with 0.25 μm of filtering after waiting reactions a period of time Device filters ultrapure water；
(7) take wherein one bottle of addition sodium hydroxide prepare leacheate, another bottle does rinse water；
(8) it is verified on ion chromatograph.
In operation it is noted that container pressure problem, prevents calcium hydroxide to be inhaled into or spray.Through the invention Experiment separation can be improved to sugar indissociable in leacheate.
The above is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, any ripe Professional and technical personnel is known, without departing from the scope of the present invention, according to the technical essence of the invention, to above Any simple modifications, equivalent substitutions and improvements etc., fall within the scope of protection of the technical scheme of the present invention made by embodiment Within.
