Description
Technical field
The invention belongs to laboratory and easily consume product field, be specifically related to tenor tearing type banded quantitatively metal three metafiltration film bar and manufacture method thereof in a kind of mensuration air.
Background technology
Present stage, at present, in ambient atmosphere, the acquisition mode of metal is mainly the air sample of suction filtration certain volume, the graininess in air and aerosolized metal is trapped in miillpore filter.Sample determination many employings atomic absorption spectrophotometry, the method needs to clear up filter membrane at experiment pretreatment stage, measures in metal transfer to solution.
In filter membrane tenor detection in, conventional quantivative approach is calibration curve method, and method, using the metallic solution of the variable concentrations directly prepared as typical curve each point drawing standard curve, measures sample concentration with this typical curve.Experiment value is deducted after the blank or reagent blank of sample blank, experiment as testing result.The detection method of the standards such as existing GBZ/T160.1-2004 to GBZ/T160.26-2004 all adopts the method.Because sample concentration is lower, the impact that reagent masking effect, container wall adsorption effect, miillpore filter material, agent formulations, oxidation rate, dissolvent residual situation, environmental baseline, atomic absorption spectrophotometer (AAS) situation etc. produce will be can not ignore, the positive-effect more than brought to sample measurement after impact superposition or negative effect degree have very big-difference because of metal species, the situation of clearing up, and all have an impact to the slope of typical curve and intercept.Calibration curve method only can deduct the deviation of typical curve in intercept to a certain extent, can not process the impact that above impact brings slope of standard curve, there is limitation, causes cannot obtaining correct measurement result during actual measurement.
Therefore need badly in the middle of prior art and want a kind of novel technical scheme to solve this problem.
Summary of the invention
Technical matters to be solved by this invention is: for test in laboratory personnel provide a kind of measure tenor in air time the preparation typical curve quantitative metallics that uses.The quantitative metallics carrier of indication of the present invention is tearing type double-layered filtration film bar.
Measure the banded three metafiltration film bars of tenor tearing type in air, it is characterized in that: comprise bolster, filter membrane protects on paper, under metal spraying filter membrane, filter membrane protect paper, described metal spraying filter membrane is between filter membrane protects on paper and filter membrane protects under paper, three is prolongation banded structure, and two of the elongated strap of three edges are bonded as one by viscose glue, or the elongated strap of three adopts the pressing of viscose glue overall crimping mode to be integrated; Described filter membrane protects on paper, to protect the elongated strap that three under paper is integrated be that axle center is wound around rolling with bolster for metal spraying filter membrane, filter membrane.
The material of described bolster is plastics or papery, and the shape of bolster is hollow or solid cylindrical structural.
The both sides of described bolster cylindrical structural are installed with the screening glass of two panels circle, and this circular screening glass is positioned at support metal spraying filter membrane below metal spraying filter membrane, and the material of this circular screening glass is plastics or papery.
Described filter membrane protects on paper, filter membrane is miillpore filter with the material of metal spraying filter membrane under protecting paper, and breakpoint location on three's breakpoint line is identical, and the spacing of the line that each breakpoint on breakpoint line is formed is equal.
Measure the manufacture method of the banded three metafiltration film bars of tenor tearing type in air, it is characterized in that:
Step one, metal spraying filter membrane and filter membrane are protected this side that paper is close to, be placed in below the vaporific spout of spray head fixed point pressurization, the pressurization of employing spray head fixed point, even vaporific spray metal salt solusion technique spray, and under metal spraying filter membrane and filter membrane protect paper, synchronized even paper feed below the vaporific spout of spray head fixed point pressurization;
Step 2, the metal spraying filter membrane after spraying coating process and filter membrane are protected paper under air-dry in 3s ~ 5s;
Step 3, filter membrane protected paper is covered in air-dry after metal spraying filter membrane on to pressurize pressing;
Step 4, filter membrane pressing be integrated protect on paper, metal spraying filter membrane, filter membrane protect the breakpoint line getting equal intervals under paper with laser breaking machine;
Step 5, the filter membrane having played breakpoint line is protected on paper, metal spraying filter membrane, filter membrane protect paper and press down and be integrated, then filter membrane is protected on paper, to protect the elongated strap that three under paper is integrated be that axle center is wound around rolling with bolster for metal spraying filter membrane, filter membrane.
In described step one, spray head is by controlling the distance with metal spraying filter membrane, and spray head spraying liquid pressure controls to spray width.
In described step one, spray head is according to metal spraying filter membrane chart drive speed under it, and in the salt solusion of spray metal, metal concentration controls tenor in metal spraying filter membrane unit area.
In described step one, spray head spray pressure is 0.5MPa ~ 5.0MPa, metal spraying width is greater than 1/4 of metal spraying material overall width, be less than 3/4 of metal spraying material overall width, chart drive speed is 0.005m/s ~ 0.2m/s, tenor in metal salt solution concentration is 0.1g/L ~ 10g/L, and metal salt solution spraying rate is 0.1L/h ~ 10L/h, and metal salt solution pH value is 5.5 ~ 8.5.
Described step 4 point of interruption distance between centers of tracks is 0.3cm ~ 3cm, and breakpoint line live width is less than or equal to 0.2nm.
The bandwidth that in described step 5, filter membrane protects on paper, metal spraying filter membrane, filter membrane protect the elongated strap that three under paper is integrated is 1cm ~ 10cm.
By above-mentioned design proposal, the present invention can bring following beneficial effect: upper and lower filter membrane of the present invention protects two edges that paper and metal spraying filter membrane band shape connects or overallly adopts viscose glue compression joint technique, prevents from producing between three being shifted.
As shown in Figure 1 and Figure 2, to manganese metal and cadmium metal, standard solution and quantitative metal filtration film of the present invention is adopted to clear up the slope of standard curve of preparation and intercept all has very big-difference.According to table 1 and Fig. 1, Fig. 2,4 typical curves measure filter membrane lead, cadmium, manganese, (cadmium 16.8 ± 1.0 μ g/ opens zinc standard substance, manganese 69.3 ± 1.0 μ g/ opens), the concentration of the standard for filter of PVD sample adopting the typical curve of quantitative metal filtration film preparation of the present invention to record is closer to actual value.Experimental result shows, and cadmium and manganese all show contrary trend at the slope of typical curve and sample recovery rate, and when the typical curve that direct employing is not cleared up measures, degree of distortion is larger.When measuring different metallic elements, adopt quantitative metal filtration film of the present invention to clear up rear drawing standard curve and can well eliminate the positive-effect or negative effect that medicine masking effect, container wall adsorption effect, filter membrane material, pretreatment mode, environmental baseline etc. bring, obtain good experimental result.
