Description
Technical field
The present invention relates to a kind of reagent using spectrophotometer detection water quality index, is specifically that one kind uses spectrophotometric
The pre-packaged reagent of lead ion content in meter detection water.
Background technology
Lead is a kind of heavy metal element for seriously endangering human health, it can influence nerve, hematopoiesis, digestion, uropoiesis, reproduction
It is nervous system and hemopoietic system with each organoid, the main target organ such as development, angiocarpy, endocrine, immune, bone.More
For the serious is the brain work(such as the growth and intellectual development that it influences infant, damage cognitive function, neurobehavioral and learning and memory
Can, severe patient causes dementia.Especially for children, academia confirms, if Pb-B than or equal to 100 micrograms per litres,
No matter either with or without clinical symptoms, sign, children's lead poisoning can be diagnosed as.Numerous studies both domestic and external show, infant and
The Pb-B of children and IQ (IQ values) are significantly correlated.1994 annual report of the World Health Organization, children blood lead levels often increase
100 micrograms per litres, IQ values averagely reduce by 1-3 points.Lead poisoning can cause intelligence to decline, and especially learning disorder occurs in children.
It is reported that the low lead children of IQ value average specifics of high lead children are 4-6 points low.Lead in natural water mostly from mining, metallurgy, chemical industry,
The pollution of the waste water such as plating, while make running water pipe using the plastic tube of leaded high pipeline or lead-containing compounds, drinking-water can be made
Middle lead content increases.So the detection strengthened to lead in water quality is extremely necessary that this is related to the physical health issues of people.Mesh
The preceding method that lead ion in water quality is detected using spectrophotometer is dithizone spectrophotometry.This method is
Using dithizone as chelating agent, be allowed to metal ion react generation band color substance, then with the spectrophotometry metal from
The method of son.This be in environmental monitoring it is common it is a kind of indirectly, extraction spectrophotometric method, be grass-roots unit's measure lead pass through frequently with
Method.Example：In water standard, the measure using dithizone spectrophotometry to lead：In the ammonia lemon that pH is 8.5-9.5
In the reductant of hydrochlorate-cyanide, lead forms the pale red dithizone lead chelate that can be extracted by the chloroform with dithizone,
Spectrophotometry can be carried out at 510nm wavelength, so as to obtain the content of lead.
The pH of dithizone and lead formation complex compound is required very high and during this method operating cost and more using reagent in this method
Not environmentally.So these problems caused by the measure of lead are developed a kind of convenient and efficient for dithizone spectrophotometry
The environmentally protective method of lead ion is necessary in ground measurement water quality.
The content of the invention
The technical problem to be solved by the invention is to provide it is a kind of can simplify detection water in lead ion operation with, inspection
Survey precision and disclosure satisfy that the pre-packaged of lead ion content in requirement, detection efficiency high, storage and detection water easy to carry
Reagent.
The pre-packaged reagent of the present invention, by solid constituent six subunit tetramines, ascorbic acid, ammonium fluoride, xylenol orange, ten
Six alkyl trimethyl amine bromides, and liquid component dilute hydrochloric acid composition, the concentration of the dilute hydrochloric acid is 8.5mL/100mL；It is described
The quality proportioning of each solid constituent is：Six 7-7.4 parts of subunit tetramines, 0.008-0.011 parts of ascorbic acid, ammonium fluoride
0.019-0.021 parts, 0.015-0.017 parts of xylenol orange, 0.015-0.017 parts of cetyltrimethylammonium bromide；It is described
The volume mass ratio of dilute hydrochloric acid and six subunit tetramines is 18mL:7-7.4g.
Preferably, the quality proportioning of each solid constituent is：Six 7.2 parts of subunit tetramines, 0.01 part of ascorbic acid, fluorine
Change 0.02 part of ammonium, 0.016 part of xylenol orange, 0.016 part of cetyltrimethylammonium bromide；The dilute hydrochloric acid and six subunits four
The volume mass ratio of amine is 18mL:7.2g.
Advantages of the present invention is embodied in：
1st, the component of reagent is solid constituent and dilute hydrochloric acid, is stored and easy to carry；
2nd, reagent using when need to only be simply mixed and add detected water sample can be directly used for spectrophotometer detect, operation
Simple and efficient, detection efficiency is high；
3rd, the Comparative result by being detected with traditional dithizone spectrophotometry, it was demonstrated that its accuracy of detection disclosure satisfy that routine
Detection demand.
Embodiment
