Description
Technical field
The present invention relates to a kind of hyperchannel heavy metal joint-detection disk.
Background technology
Heavy metal mainly contains gold, silver, copper, lead, nickel, cobalt, chromium, mercury, cadmium and arsenic etc., wherein the harm maximum is had lead, mercury, chromium (VI), copper and a cadmium etc.As: lead has cumulative bad, can be by the absorption of intestines and stomach, infringement nervous system, hemopoietic system and digestive system reduce immunity of organisms; Mercury easily is bioaccumulation, and makes the people poisoning by food chain, produces neuropsychiatric disorders, and even " minamata disease "; The Cadmium toxicity effect also directly suppresses some enzyme system, and liver, kidney and bone tissue is damaged except the metabolism of disturbing copper and zinc, thereby causes " the bone pain is sick " and renal dysfunction.At present, the water body of China's trunk river, lake and underground water descends because heavy metal pollution causes Water quality and water supply quality; Farmland and vegetable field soil are irrigated by the water of heavy metal pollution, make agricultural product and vegetable and fruit heavy metal pollution serious, and drinking-water and food security in serious threat, and heavy metal pollution and poisoning accident emerge in an endless stream.
The conclusive evidence analytical approach that common approved heavy metal detects has: but ultraviolet spectrophotometric method, atomic absorption method, atomic fluorescence method, inductively coupled plasma method, X-fluorescence spectrum, inductively coupled plasma mass spectroscopy and inductively coupled plasma mass spectroscopy etc., although these instrument analytical methods are sensitive reliable, but required instrument is complicated, need the specialty analysis personnel operation, testing cost is high, must complete in the laboratory, be difficult to use it for the Site Detection analysis of drinking-water and food samples.Although test paper method sensitivity is relatively poor, but have simple to operate, Site Detection advantage fast and easily, but conventional test strip can only detect a kind of heavy metal target thing at every turn, for the contents of many kinds of heavy metal ion that contains in sample, need multiple test strips repeatedly to test, and can not satisfy the detection for the less sample of amount of liquid.
Not yet find at present to utilize support based on ultrafine fiber, can be used for that on-the-spot contents of many kinds of heavy metal ion detects, quick and convenient and practical multichannel combined Test paper disk.
Summary of the invention
The objective of the invention is to overcome the deficiency that various heavy is difficult to carry out simultaneously Site Detection, provide a kind of height integrated, can be used for the scene, the hyperchannel heavy metal joint-detection disk that supports based on ultrafine fiber that can complete quickly and easily that various heavy detects simultaneously.
Technical scheme of the present invention is summarized as follows:
The hyperchannel heavy metal joint-detection disk that supports based on ultrafine fiber, formed by circular cover (3) and the circular substrate (1) that is provided with radially 2-5 the groove (2) of arranging, bottom at described groove is provided with ultrafine fiber, be provided with heavy metal and detect filter paper on described ultrafine fiber, the center of described circular cover is provided with well (4), and described circular cover is connected connection with the circular substrate edge.
The material preferably clear tygon of circular cover or transparent poly-the third ethene.
The material of circular cover can also be selected Polyvinylchloride, when selecting Polyvinylchloride, is provided with observation window at the groove of corresponding circular substrate.
The preferred 4-5 of the number of groove.
Ultrafine fiber preferably polytetrafluoroethylene base ion-exchange ultrafine fiber.
The preferred 4-15cm of the diameter of circular cover.
The preferred 0.1-1.0cm of the diameter of well.
Heavy metal detects the detection filter paper that filter paper is selected from lead, mercury, chromium (VI), copper and cadmium.
Super-fine fiber material has strong absorption property to the heavy metal ion such as lead, copper, mercury, cadmium, chromium (VI) and arsenic (V) in water, can adsorb quickly and efficiently with the enrichment fluid sample in heavy metal element, and adsorbance is large; By the syphonic effect of ultrafine fiber, make liquid can be reached rapidly the detection filter paper zone of end by initiating terminal.Therefore, this Test paper adopts ultrafine fiber as supporting layer, has increased the separation and concentration usefulness of test paper to target, and has greatly shortened detection time.
The hyperchannel heavy metal joint-detection disk that supports based on ultrafine fiber of the present invention, can complete quickly and easily various heavy in 10 minutes detects in as lead, mercury, chromium, copper, cadmium, need not the professional and technical personnel, simple to operate, use at the scene that can be widely used in health and epidemic prevention, supervision, quality inspection and environmental monitoring department, and can be heavy metal pollution accident examination foundation is provided.

Get the industrial pollution wastewater sample 500 μ L that contain lead, mercury, chromium (VI), copper and cadmium with common Filter paper filtering one time, remove particulate solid, detect lead, cadmium, copper through atomic absorption spectrophotometry; With hydride generation atomic fluorescence spectrophotometry mercury; Diphenyl carbazide spectrophotometry detects chromium (VI), and the concentration of lead, mercury, chromium (VI), copper and cadmium respectively is: 15.6,7.5,5.7,5.4 and 12.8mg/L., getting filtered solution 350 μ L directly is added dropwise in well 4, filtered solution is by siphon and the capillary action of ultrafine fiber, the heavy metal that can connect to each passage ultrafine fiber fast detects filter paper and flows, reagent on its corresponding detection filter paper reacts, observe each heavy metal in 10 minutes and detect filter paper, result: the plumbous filter paper that detects becomes rose by apricot, mercury detects filter paper and becomes aubergine by lightpink, chromium (VI) detects filter paper and becomes aubergine, copper detects filter paper by the colourless look of flavescence gradually, cadmium detects filter paper and becomes darkorange by yellow, and carry out the color range comparison with standard color comparison card (Fig. 4), thereby the sxemiquantitative of carrying out concentration of heavy metal ion is judged.Through comparing with the standard color range, the sxemiquantitative concentration of lead, mercury, chromium (VI), copper and cadmium is respectively 10,8, and 6,6 and 10mg/L.It is little that the concentration of the various heavy that detects with this hyperchannel heavy metal joint-detection disk and the instrumental method of standard are compared difference.
Embodiment of the present invention is illustrative; but not determinate; above-described embodiment just helps to understand the present invention; therefore the present invention is not limited to the embodiment described in embodiment; every those skilled in the art belong to the scope of protection of the invention equally according to the embodiment that goes out of technical scheme of the present invention.
