Description
Technical field
The present invention relates to a kind of reagent using spectrophotometer to detect water-quality guideline, specifically a kind of pre-packaged reagent using spectrophotometer to detect lead ion content in water.
Background technology
Lead is a kind of heavy metal element of serious harm human health, and each organoid such as it can affect the nerves, hematopoiesis, digestion, uropoiesis, reproduction and development, cardiovascular, endocrine, immunity, bone, main target organ is nervous system and hemopoietic system.More seriously it affects growth and the intelligent development of infant, and the brain functions such as damage cognitive function, neurobehavioral and learning and memory, severe patient causes dementia.Particularly for children, academia confirms, as long as Pb-B exceedes or equals 100 micrograms per litre, no matter whether has clinical symptoms, sign, can be diagnosed as children ' s lead poisoning.Large quantity research both domestic and external shows, the Pb-B of infant and children and IQ (IQ value) significant correlation.The World Health Organization (WHO) 1994 annual report, lead levels often increases by 100 micrograms per litre, and IQ value on average reduces by 1-3 points.Saturnism can cause intelligence to decline, and especially children there will be learning disorder.It is reported, the low plumbous children of IQ value average specific of high plumbous children are low 4-6 points.The many pollutions from the waste water such as mining, metallurgy, chemical industry, plating of lead in natural water, use the plastic tube of leaded high pipeline or lead-containing compounds to make running water pipe simultaneously, lead content in drinking-water can be made to increase.So strengthen extremely being necessary detection plumbous in water quality, this is related to the physical health issues of people.The method that current use spectrophotometer carries out detecting lead ion in water quality is mainly dithizone spectrophotometry.This method is sequestrant with dithizone, makes it to react to generate with metallic ion to be with color substance, then by the method for this metallic ion of spectrophotometry.This is that the one commonly used in environmental monitoring is indirect, extraction spectrophotometric method, is the method that grass-roots unit measures plumbous often employing.Example: in water quality standard, adopt dithizone spectrophotometry to the mensuration of lead: to be in the reductant of ammonia citrate-prussiate of 8.5-9.5 at pH, plumbous formation with dithizone can by the plumbous chelate of the pale red dithizone of chloroform extraction, can spectrophotometry be carried out at 510nm wavelength place, thus obtain plumbous content.
In this method, dithizone requires very high with the plumbous pH forming complex compound, and during the method operating cost and use reagent is not environmentally many.So for dithizone spectrophotometry to these problems caused by the mensuration of lead, the environmental protection method developing lead ion in a kind of water quality of measurement is quickly and easily necessary.
Summary of the invention
Technical matters to be solved by this invention is, provide a kind of can simplify the operation that detects lead ion in water with, accuracy of detection can meet request for utilization, detection efficiency high, store and the pre-packaged reagent of lead ion content in detection water easy to carry.
Pre-packaged reagent of the present invention, by solid content six subunit tetramines, ascorbic acid, ammonium fluoride, xylenol orange, hexadecyl trimethyl ammonium bromide, and liquid component watery hydrochloric acid composition, the concentration of described watery hydrochloric acid is 8.5mL/100mL; The quality proportioning of described each solid content is: six subunit tetramine 7-7.4 parts, ascorbic acid 0.008-0.011 part, ammonium fluoride 0.019-0.021 part, xylenol orange 0.015-0.017 part, hexadecyl trimethyl ammonium bromide 0.015-0.017 part; Described watery hydrochloric acid is 18mL:7-7.4g with the volume mass ratio of six subunit tetramines.
Preferably, the quality proportioning of described each solid content is: six subunit tetramines 7.2 parts, 0.01 part, ascorbic acid, ammonium fluoride 0.02 part, xylenol orange 0.016 part, hexadecyl trimethyl ammonium bromide 0.016 part; Described watery hydrochloric acid is 18mL:7.2g with the volume mass ratio of six subunit tetramines.
Advantage applies of the present invention exists:
1, the composition of reagent is solid content and watery hydrochloric acid, store and easy to carry;
2, only need when reagent uses simply to mix and add detected water sample and can be directly used in spectrophotometer detection, simple and efficient to handle, detection efficiency is high;
3, by the Comparative result with traditional dithizone spectrophotometry, prove that its accuracy of detection can meet conventional sense demand.
Embodiment
The pre-packaged reagent of the embodiment of the present invention, is made up of six subunit tetramines, hydrochloric acid, ascorbic acid, ammonium fluoride, xylenol orange, hexadecyl trimethyl ammonium bromide.The concrete configuration of this plumbous pre-packaged reagent is that every 25mL detected water sample need add 7.2 grams of six subunit tetramines, 18mL watery hydrochloric acid (8.5mL/100mL), 0.01 gram of ascorbic acid, 0.02 gram of ammonium fluoride, 0.016 gram of xylenol orange, 0.016 gram of hexadecyl trimethyl ammonium bromide.Wherein six subunit tetramines are white crystal, and watery hydrochloric acid is liquid, and ascorbic acid is clear crystal, and ammonium fluoride is white or the crystallization of water white transparency rhombic system, and xylenol orange is rufous crystalline powder, and hexadecyl trimethyl ammonium bromide is white micro-crystals powder.For the liquid component in this plumbous pre-packaged reagent and solid constituent, consider all the components factor easily reacted packaging together, select with two reagent bottles, fill liquid component (watery hydrochloric acid) and the solid constituent (six subunit tetramines, ascorbic acid, ammonium fluoride, xylenol orange, hexadecyl trimethyl ammonium bromide) of plumbous pre-packaged reagent respectively.For the specification of two reagent bottles, can according to reality detect required plumbous pre-packaged reagent number determine the specification of reagent bottle to ensure that directly can get plumbous pre-packaged reagent when detecting detects at every turn.Two are equipped with respectively to the reagent bottle of liquid parts and solid state component, consider the chemical property of reagent, under two reagent bottles should be made should to be placed on the environment of lucifuge low temperature drying, when guaranteeing to use, ensure the reliability detecting data.
Use the concrete steps of lead ion in this pre-packaged reagent measuring water quality as follows:
