Abstract
The present invention is a kind of method quickly detecting toxic gas NO using metalloporphyrin solution.For this method using the solution of CoTPP, Tetraploid rice, tetraphenylporphyrin magnesium, tetraphenylporphyrin nickel, tetraphenylporphyrin copper and/or four p-methoxyphenyl Cobalt Porphyrins as detection agent, solvent is dichloromethane, chloroform, methanol, ethyl alcohol or dimethyl sulfoxide (DMSO).A concentration of 0 6.0 × the 10 of solution‑5Mol/L completes detection at room temperature to the gas to be detected of a concentration of 0 1000ppm containing NO in 10min.This method have easy to operate, mild condition, be swift in response the advantages such as sensitive, have important practical significance for the detection and identification of toxic gas NO.
Description
Technical field
The present invention is a kind of method of detection toxic gas NO quick at ambient temperature.Belong to environmental monitoring.
Background technology
NO is one of main polluted gas, even more one of the ingredient of power plant flue gas in air, it can not only destroy ozone
Layer causes the environmental hazards such as acid rain, can also generate high risks to health.NO can be with the hemoglobin knot in blood of human body
It closes, so that blood oxygen carrying capacity is declined, cause body anoxic；In addition, NO has carcinogenesis, it can be to cell division and hereditary information
Generate harmful effect.
The detection method of toxic gas NO has conventional a chemical measure and spectroscopic method, and conventional chemical measure
Measuring surface is narrow, and a kind of method can only survey a kind of gas, and detection time is long, can not be detected in due course.So mostly logical at present
The method for crossing instrument carries out the detection of NO, such as laser spectrometry, photon ionization spectroscopic methodology, photocaustic spectroscopy, Difference Absorption light
The instrumental methods such as spectrometry, laser irradiation fluorescence method, fluorescence probe and electrochemistry acusector.Although instrument has high sensitivity, sound
It answers the advantages that wide, but large-scale instrument operating condition is relatively harsh, and inconvenient to carry.
For this purpose, a kind of method of reagent detection toxic gas NO of invention, at normal temperatures and pressures, it can be achieved that low
The fast selective of concentration NO detects, this has very important practical significance to the detection of toxic gas NO.
Invention content
It is detection agent that the object of the present invention is to provide a kind of using metalloporphyrin solution, and quick, Sensitive Detection low concentration has
The method of poisonous gas NO.
The present invention detection agent be CoTPP, Tetraploid rice, tetraphenylporphyrin magnesium, tetraphenylporphyrin nickel,
The metalloporphyrins solution such as tetraphenylporphyrin copper and/or four p-methoxyphenyl Cobalt Porphyrins；The solvent of the metalloporphyrin solution
It is dichloromethane, chloroform, methanol, ethyl alcohol or dimethyl sulfoxide (DMSO).
The present invention utilizes a concentration of 0-6.0 × 10 of above-mentioned metalloporphyrin solution-5Mol/L, to containing a concentration of 0- of NO
The gas to be detected of 1000ppm completes detection at room temperature in 10min.
Specific implementation mode
The present invention is described with reference to specific embodiment, i.e., a kind of utilization metalloporphyrin solution quickly detects toxic
The method of gas NO.Specific implementation mode is as follows：
Embodiment 1：
With CH3OH is solvent, using four p-methoxyphenyl Cobalt Porphyrins as detection agent, is made into 6.0 × 10-5The solution of mol/L.
Being passed through gas to be checked at room temperature (may contain NO, N2、CO、CO2、H2S etc.), the color of 10min solution becomes from original pink
Brown color contains NO that is, in gas, NO is otherwise free of in gas (see Fig. 1).
Embodiment 2：
With CH2Cl2For solvent 4.5 × 10 are made into using tetraphenylporphyrin copper as detection agent-5The solution of mol/L.At room temperature
Being passed through gas to be checked (may contain NO, N2、CO、CO2、H2S etc.), the color of 5min solution rose pink becomes brown green from original
Color contains NO that is, in gas, NO is otherwise free of in gas (see Fig. 2).
Embodiment 3：
With CHCl3For solvent 3.0 × 10 are made into using tetraphenylporphyrin nickel as detection agent-5The solution of mol/L.Lead at room temperature
Entering gas to be checked (may contain NO, N2、CO、CO2、H2S etc.), the color of 2min solution becomes green, i.e. gas from original pink
Contain NO in body, NO is otherwise free of in gas (see Fig. 3).
