Description
Technical field
The present invention relates to the technical fields of electrolysis field semi-permeable membrane, and in particular to a kind of electrochemistry experiment is used to hold
Electrolyte allows making and the application method of the freely through capsule cup of zwitterion.
Background technology
The characteristics of semi-permeable membrane is with allowing zwitterion to pass freely through, and molecule and particle being prevented to pass through.It can be directly used for
Field trash electrolytic experiment can allow zwitterion by ensureing the smooth generation of electrolytic process and by target field trash grain
Son is successfully retained in semi-permeable membrane capsule cup, not only reduces doing for cathode and external environment to greatest extent again simultaneously convenient for collecting
It disturbs.And the shortcomings that semi-permeable membrane that conventional art makes, mainly includes that manufacture craft is cumbersome, inconvenient for use and intensity is not high, such as specially
Profit《Semi-permeable membrane rubber bag for electrolysis and preparation method thereof》The gauze bag used in (publication number CN 101239282A), by capsule liquid
It is poured on the glass mold for being cased with gauze bag, forms the semi-permeable membrane poly-bag with gauze, and need additional retainer ring of formulating will
The fixation of semi-permeable membrane poly-bag could use, and not only technique is cumbersome, complicated for operation, and the presence of gauze bag makes capsule liquid be difficult to uniformly
It is flowed down along mold, causes the collapsible bag uneven thickness made, be easily broken, and have an impact for semi-transparency type.The present invention is very
It solves more than problem well, can conveniently and efficiently produce the capsule cup that intensity is high, semipermeability is good.
Invention content
The technical problems to be solved by the invention be provide for the above-mentioned prior art it is a kind of make it is simple, easy to use,
The semi-permeable membrane capsule cup that semipermeability is good and intensity is high solves electrolysis field trash experiment Anodic sample and is difficult to stablize electrolysis and mesh
Inclusion particle be difficult to the problem collected.
Technical solution is used by the present invention solves the above problems：A kind of electrolysis semi-permeable membrane capsule cup, feature exist
In：Including capsule cup body, the rim of a cup of capsule cup body is provided with annulus, and the annulus is coated entirely, extends extension on the outside of annulus
Capsule cup body can be vacantly arranged in electrolytic cell by frame structure by the hanging rack structure.
The above-mentioned electrolysis preparation method of semi-permeable membrane capsule cup, includes the following steps
(1) material prepares
Prepare annulus and cup mould, the outside diameter of the interior bore and cup mould of annulus are coincide, annulus can just hanging sleeve stand upside down
Cup mold cup mouth do not fall；
(2) capsule liquid is configured
Cellulose acetate is taken to be dissolved in solvent, is capsule liquid fully after dissolving；
(3) capsule cup is prepared
Annulus is sleeved on the cup mould put upside down, support be allowed to hold up it is hanging, by the capsule liquid that step (2) prepares along cup mould bottom
Portion uniformly pours out for one week, and capsule liquid is slowly flowed down along smooth cup mould outer wall up to being paved with entire cup mould and coating annulus, quiet
Type is set to, trims part extra below annulus；
(4) it impregnates
The whole device trimmed is put into the container being filled with water and is impregnated, solvent is allowed to be dissolved into water body, makes capsule abundant
Solidification forms the capsule cup with semi-permeable membrane on cup mould；
(5) it demoulds
After capsule cup body fully solidifies, in water body, a glass mould is pinched on one side, the hanger of annulus is shaken on one side, makes capsule
Cup body is completely removed from cup mould, the capsule cup as with annulus.
Preferably, the concentration of step (2) capsule liquid meets per 500mL solvents dissolving 40-50g cellulose acetates, this concentration
It can obtain the capsule cup body that thickness is enough, intensity is high down, it is excessively high to be unfavorable for semi permeability, it is too low to be unfavorable for shaping and demoulding.
Preferably, step (3) time of repose 3-5min completes pre-profiling, is that solvent is allowed to volatilize during standing, capsule liquid
Primary crystal.
Preferably, step (4) soaking time is 3-5min, and solvent is made fully to be dissolved into water body, and solvent is good water solubility,
On the one hand cooling one side lyosoption is impregnated, accelerates crystalline forming.
The application capsule liquid, which will pass through, stands and impregnates two procedures, and the preferred acetones of solvent are volatile, good water solubility
Solvent.
The application method of the application semi-permeable membrane capsule cup and electrolysis application method：By the hanger on the outside of annulus by glue
Capsule cup is vacantly hung in electrolytic cell, and anolyte is held inside capsule cup, and sample is hung and is dipped in anolyte, electricity
Solution preocess capsule cup allows zwitterion normal through and the field trash, the carbide intended particle that come off from sample are collected in glue
In capsule cup.
Compared with prior art, the advantage of the invention is that：
1st, the present invention in increase band hook annulus, it is simple and effective solve capsule cup obtained be difficult to fix cause to make
With inconvenient problem.Annulus becomes an entirety with the perfect adaptation of capsule cup body at the time of molding, and capsule cup is allowed more may be used in fixation
To improve the use intensity of capsule cup to a certain extent.
2 present invention devise the specific ingredient of capsule liquid, and pass through the concentration for improving cellulose acetate in a certain range
Increase the use intensity of capsule cup obtained, many experiments determine the optimum proportioning of cellulose acetate and solvent (acetone), make
Under the premise of capsule cup semi permeability effect and manufacturing process is not influenced, increase cellulose acetate concentration as possible, so as to maximum limit
The thickness of the increase capsule cup of degree increases its intensity with this, overcome by using gauze bag increase poly-bag intensity the defects of
(patent《Semi-permeable membrane rubber bag for electrolysis and preparation method thereof》(publication number CN 101239282A)), it is needed in being made such as gauze bag
Exceptionally straight on tube wall, adjusting tightness is moderate, and not only manufacturing process requirement is high, operation difficulty is big, and the presence of gauze bag makes glue
Cyst fluid is difficult to uniformly flow down along mold, causes collapsible bag wall thickness uneven, easily forms stress concentration, cause to rupture.
3rd, semipermeability capsule cup produced by the present invention can be applied to the high standards exact tests such as electrolysis field trash, facies analysis
In, anolyte is contained in capsule cup by when experiment, can allow zwitterion by ensure electrolytic process it is smooth into
Row, and the field trash not being electrolysed and releasing characteristics can be successfully retained in semipermeability film, it is both same convenient for what is collected
When shield the interference of cathode and external environment to the maximum extent again.
4th, the capsule cup that the application makes is simple and convenient, at low cost and can recycle, and is used directly for batch sample
In the experiment that product examine is surveyed.
5th, those of ordinary skill in the art can be familiar with the method quickly, to be engaged in the experiment of electrolysis field trash and mutually dividing
The technical staff of analysis experiment provides new experimental considerations.
