Description
Technical field
The invention belongs to heavy metal ion rapid detection technical fields, are specifically related to a kind of lead ion Test paper and its system
Preparation Method and application method.
Background technology
Lead is a kind of heavy metal element seriously endangering human health and the larger one kind of heavy metal pollution Poisoning,
Lead can enter human body by air, food, water, once it is difficult to exclude into human body.It can influence nerve, hematopoiesis, digest, secretes
Each organoid such as urine, reproduction and development, angiocarpy, endocrine, immune, bone, lead harm is the most serious is nervous system and makes
Blood system, Mental retardation caused by lead are irreversible, and after driving lead treatment, blood lead declines, but Mental retardation is without apparent
Restore.
Lead has different people different degrees of harm, the lead poisoning of pregnant woman's period of gestation can influence the development of fetal nerve plate, sternly
The meeting of weight causes fetus to return shallow, feeblemindedness at congenital cerebral sulci;It is unmarried youth men and women's lead poisoning can cause it is infertile, even if
Fertility offspring also results in offspring's physique and oligrophrenia;Children's lead poisoning is damaged most serious with nervous system, can cause
Children have the fidgets, and personality change is slow in reacting, and intelligence, decrease of memory etc., severe patient may occur in which lead encephalopathy, even
It is dead;The elderly's lead poisoning can cause dull-witted, brain death is busy etc..
Currently, in the exploitation of lead ore and leaded metallic ore;It smelts, lead pig, stereotype, lead pipe and other leadworks is melted;Print
Typefounding, casting version in brush industry;The melting of the Storage Battery Industry in China, casting grid;Welding and fusion cutting containing lead metal and are coated with leaded paint
Metal product;Ceramics, enamel, cloisonne enamel match glaze using lead compound;Using containing lead pigments etc. in plastic processing, paint production
It is all easy to touch lead, lead is not that for the moment, can also endanger the next generation to the harm of human body.
Therefore, lead content detection is of great significance to human health and social development, so just with greater need for one kind
Fast detecting tool easy to operate, accuracy is high, cheap can both meet family's self-test, can also meet enterprise's production
Detection demand can be widely used in the inspection detection of soil, water quality, environment, cosmetics, food, all types of industries product.
Invention content
In consideration of it, the invention is intended to provide a kind of lead ion Test paper and preparation method thereof and application method, the test paper
Reagent type is few needed for preparing, and preparation method is simple, free from environmental pollution, applied widely, easy to operate, accuracy is high, price
Cheaply.
To achieve the above object, present invention employs following technical proposals
A kind of lead ion Test paper, including:Bar shaped substrate and the test-paper for being fixed on bar shaped substrate, wherein test-paper
It is infiltrated in maceration extract by filter paper, dry cut is made after taking-up, and the test paper maceration extract component is by 0.05-0.2g neighbour's Féraud
Quinoline, 0.1-0.3g polyethylene glycol, 0.05-0.2g xylenol orange, 1.0-3.0mLOP- emulsifiers composition, and acid, which is added dropwise, makes the system be in
It is acid.
The hydrochloric acid that the acid is 1-3 drops 1moL/L, naturally it is also possible to use sulfuric acid and nitric acid.
More specifically, the bar shaped substrate is equipped with test paper paste-side and grip end, test-paper is fixed on test paper paste-side
On.
The preparation method of lead ion Test paper of the present invention, specifically includes following steps:
Step 1:Complex reaction can occur with the lead ion in sample in acid condition according to xylenol orange, generate purple
The chemical principle of red compound, the maceration extract are made by following steps:
A. 0.1000g Phens are weighed to be dissolved in 100mL distilled water, maceration extract is made in heating stirring dissolving on electric furnace
Ⅰ;
B. 0.2000g polyethylene glycol and 0.1000g xylenol orange are weighed, is added in cooling maceration extract I and dissolves, leaching is made
Stain liquid II;
C. 2.0mLOP- emulsifiers are added in maceration extract II, and a small amount of hydrochloric acid, which is added dropwise, makes system at acidity, is sufficiently stirred
Uniformly to get test paper maceration extract;
Step 2:The filter paper cut out is slowly immersed in test paper maceration extract, filter paper takes out after being impregnated in test paper maceration extract,
Drying;
Step 3:This test-paper is pasted on item by the test-paper that the filter paper of drying is cut into required specification on instrument
Lead ion Test paper is made in shape substrate.
Further, filter paper takes out after impregnating 10-15min in test paper maceration extract, is laid on clean glass plate, sets
In baking oven, 2-3h are dried at 35-40 DEG C to dry.
Further, manufactured test paper need to be protected from light, 0-30 DEG C dry of storage under room temperature, be sure not directly sudden and violent
Dew is in air.
