The invention discloses a preparation method of a giant-scale porphyrin microcapsule and an application of the giant-scale porphyrin microcapsule preparation method. The preparation method contains the following steps of: 1) preparing a porphyrin-containing mixed solution by using a mixed solution of benzene and 1,2-dichloroethane as a solvent; and 2) preparing the microcapsule by the utilization of a three-way micro fluidic technology, using an aqueous solution as internal and external phases, drying and collecting under a suitable condition. The giant-scale porphyrin microcapsule prepared by the method of the embodiment is used for detection of heavy metal ions in a solution. The preparation method provided by the invention is simple, and the giant-scale porphyrin microcapsule obtained by the preparation method has high sensitivity to heavy metal ions.
Description
Technical field
The invention belongs to the microcapsules preparation field, the concrete preparation method who relates to a kind of huge porphyrin microcapsules.
Background technology
Along with the raising day by day of material life, heavy metal when facilitating for life, atmosphere, water body, the environment that the mankind such as soil depend on for existence, all in various degree pollutions that receives heavy metal, and serious day by day.Heavy metal generally is meant proportion greater than 5 metal, nearly 45 kinds, and like copper, lead, gold, silver, iron, zinc, cobalt, mercury, violent, cadmium, nickel etc.These metals mostly affect human health, and manganese, zinc, iron etc. are the required trace elements of vital movement, and most of heavy metal has serious toxicity injury like lead, mercury, cadmium etc. to human body, and are wherein maximum to human harm with lead, mercury, cadmium, arsenic, chromium etc.But these heavy metals are also being played the part of very important role simultaneously in commercial production.In the time of industrial development, a lot of problem of environmental pollutions have also been brought.Aspect environmental pollution, heavy metal pollution has the heavy metal pollution of remarkable toxicity except mercury, lead, cadmium etc., also comprises the discharging of some needed by human body excessive microelements and the environmental pollution and the injury of human that cause.The heavy metal of part can not be by biodegradation, the enrichment of the biological magnification thousandfold through food chain.According to a guide that U.S. CDC is announced, blood lead concentration is at 10 μ gdL
-1Be regarded as when following " health ", be higher than 20 μ gdL at blood lead concentration
-1In time, just need to treat.Yet big quantity research shows, also can cause damage to human body even the lead of low concentration exposes, and especially influences infant and children's brain development.Therefore, to the detection of environment and body weight for humans metal exposed level, especially low-level detection is of great importance to health of people.
Plumbous: as can in human body and animal tissue, to accumulate, in the lead of the annual consumption in the whole world, probably have 40% to be used for battery manufacturing, 20% and to join gasoline, 12% and be used for construction material.Lead can pass through in skin, alimentary canal, the respiratory tract entering body, and can in human body, accumulate for a long time.
Cadmium: toxicity is very big, can accumulate in vivo, mainly accumulates at kidney, and the damage urinary system and has teratogenesis, mutagenesis, and in 12 kinds of dangerous chemicals with global meaning, cadmium is classified as the first place.The pollution of cadmium is mainly derived from mining and smelting, and plating, battery, plastics, coating etc.
Mercury: and compound all belongs to extremely toxic substance, mercury metal mainly with steam-like in respiratory tract gets into body, the mercury metal in the blood causes irreversible damage to central nervous system after getting into brain tissue.The inorganic mercury ion can change into the bigger organic mercury of toxicity, gets into human body by food chain, causes toxic reaction.The pollution of mercury is mainly derived from aspects such as illumination, precious metal smelting, cosmetics, instrument, fire coal.
Arsenic: mainly be present in the environment with positive trivalent and positive pentavalent attitude, wherein the trivalent arsenic compound is stronger than other arsenic compound toxicity.Arsenic can pass through respiratory tract, alimentary canal and skin contact and get in the body, and can in human body, accumulate by multiple organ, causes the pathology of many organs.Arsenic contamination is mainly derived from the three waste discharge of chemical industry, metallurgy, thermal power generation, papermaking, leather, electronics industry etc.
Chromium: mainly exist with trivalent chromium and two kinds of valence states of Cr VI.Pollution of chromium mainly is industrial wastewaters such as plating, pickling of metal, leather in the water, and wherein Cr VI is mainly derived from the discharge of wastewater of Electroplate Factory, and trivalent chromium is mainly derived from the waste water of Leather Factory, dyestuff factory, pharmaceutical factory etc.Chromium can advance alimentary canal, respiratory tract and skin and get in the body, causes the damage of human body.
From above-mentioned a few heavy metal species features of pollution; The pollution of the heavy metal industrial pollution of originating like this; But the every aspect of affect people's life, people's required requirement of living: food, water, clothes, daily necessities etc. all have the possibility that faces heavy metal pollution.Therefore, all need detect in every field such as agricultural, environment, biological medicine, industry heavy metal.
Summary of the invention
The object of the invention aims to provide a kind of preparation method of huge porphyrin microcapsules.
Another object of the present invention is the practical application through the huge porphyrin microcapsules of method preparation of the present invention.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
The present invention is by the benzene that contains porphyrin: 1, and 2-dichloroethanes mixed solution is accomplished.
The preparation method is dissolved in benzene with porphyrin finite concentration proportioning: 1, and among the 2-dichloroethanes mixed solution, utilize the mixed solution that obtains to prepare huge microcapsules then through microflow control technique.Concrete grammar is following:
1) use benzene: 1,2-dichloroethanes mixed solution is done the solution that the solvent configuration contains porphyrin;
2) utilize the triple channel microflow control technique to prepare microcapsules, interior phase and foreign minister use the aqueous solution, and dry under optimum conditions the collection.
The present invention has following beneficial effect:
The present invention utilizes porphyrin as detection material,, has the following advantages as carrier with microcapsules:
1. the microcapsules that contain porphyrin can utilize porphyrin to carry out the detection of heavy metal ion in the solution for the sensitiveness of heavy metal ion;
2. method is simply effective, and is easy and simple to handle, and required time is shorter.
3. preparation facilities is simple, and what special devices the present invention does not need, and common threeway microfluidic system just can meet the demands;
4. store easily: the huge microcapsules of the porphyrin of acquisition have good stability, and the porphyrin in it exists stable, can preserve for a long time;
5. applied range: porphyrin all has comparatively responsive response characteristic to most of heavy metal ion, can be used to detect most of heavy metal ion;
6. nontoxic: the material of selecting for use all is a bio-compatible or degradable, thus all as safe as a house to bacterium and environment, be extraordinary ecological environment material nd.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment detailed description of the present invention.
